8*9 we know mutliplication can be seen as repeated addition 8*9=8+8+8+8+8+8+8+8+8=72 but i want to introduce you to the new operation called exponets which can we used as repeated multiplication say we get 89 denote it is repeated mutliplication we get 89=8*8*8*8*8*8*8*8*8=134,217,728 lets try another one 27=2*2*2*2*2*2*2=128 lets try last one 1010=10*10*10*10*10*10*10*10*10*10=10,000,000,000 now i want you to try thr try of the exersizes on your own and see how far you get

​we know that 73=7*7*7=343 and 107=10*10*10*10*10*10*10=10,000,000 but what if we have an negative power well we are going to use a formula if a-n is the case than
a-n=1/an say we got 8-4=1/84=1/4,096 we are going to try few examples say we have 7-2=1/72=1/49 and another one 10-9=1/109=1/1,000,000,000 and another one
5-3=1/53=1/125 and another one 2-12=1/212=1/4,096 what if we encounter 90 note anything raised to the 0th power is 1 so 90=1 always remember anything raised to 0 is 1 no debate on it now i want you to try the rest of the excerises on your own and see how far you get

​say we get 2123 you might say since were multiplying we should multiply the exponents but you are wrong we add then using the following rule anam=an+m we can do the same with our problem heres the solution 2123=21+3=24=16 if you try using other method like 2123=21*23=2*8=16 you are going to get the same answer say i got another ploblem 3233 to solve that use anam=an+m solve it while using a method formula 3233=32+3=35=243 lets try another method 3233=32*33=9*27=243 lets try another one 7173 using the formula anam=an+m to solve it so 7173=71+3=74=2,401 try another way 7173=71*73=7*343=2,401 lets the last one 6364 using the formula anam=an+m to solve it so 6364=63+4=67=279,936 if you try another method we get 6364=63*64=216*1,296=279,936 now i want you to try the rest of the excerises on your own and see how far you get.

​say i got 73/72 and i want to divide then you might think we can divivde the expoents but you are wrong we subtract them using this rule an/am=an-m we can apply the same method on the ploblem we got so 73/72=73-2=71=7 if you done a different method like this 73/72=343/49=7 you are going to get the same result lets try another one 4/4-3 again use the dividing formula with exponents an/am=an-m so 4/4-3=41/4-3=41-(-3)=41+3=44=256 lets try another one 8100/897 again use the same dividing with exponents formula an/am=an-m lets apply the same interperatation 8100/897=8100-97=83=512 you might try using a calculator but it isnt neccesary so always use the quick method we give you now i want you to try the rest of the excerises on your own and see how far you get

​say i got an expression √(3√(729)) to do that we have to use the root product formula which is n√(m√(a))=nm√a why because this n√(m√(a))=(m√(a))1/n=((a)1/m)1/n=a1/mn=nm√a see why now lets apply the same thing √(3√(729))=2*3√729=6√729=3 another way to prove it is like this √(3√(729))=√9=3 i wont explain this way i want you to explain it on your own anyways lets try another one 3√(4√(1,000,000,000,000,000,000,000,000)) again multiply the roots like this n√(m√(a))=nm√a lets apply the same thing 3√(4√(1,000,000,000,000,000,000,000,000))=3*4√1,000,000,000,000,000,000,000,000

​say we got 81.25 and we want to evaluate it so what we could do is to convert decimals into exponents so we know .25=1/4 so why wont you to do the same thing like you did in the past so we get 81.25=811/4=4√81=3 plain simple lets try another one
729.5 like we did previously convert decimals into fractions you can also convert percents into fractions using 2 steps anyhow .5=1/2 use the same interperatation we get 729.5=7291/2=√729=27 lets try another one 100,000,000.25 same thing convert decimals to fractions we get .25=1/4 use the same interperatation we get 100,000,000.25=100,000,0001/4=4√100,000,000=100 lets try another one 2,401.25 lets convert decimals in fractions we get .25=1/4 lets use the same interpretation on the ploblem we get we get 2,401.25=2,4011/4=4√2,401=7 lets try the last one 1,000,000,000.
7 again convert decimals into exponets we get .7=7/9 use the same interperation we get 1,000,000,000.7=1,000,000,0007/9=9√1,000,000,0007=9√1e+63

​lets say i got an equation (5x2y3)3 and we want to solve it to do that we need to separate them or use the rule (anbm)k=ankbmk (anbm)k=(an)k(bm)k=ankbmk or we get (5x2y3)3=(5)3(x2)3(y3)3=125x2*3y3*3=125x6y9 lets try another one say i got (9u4v5)4 to solve it we separate them we get (9u4v5)4=(9)4(u4)4(v5)4==6,561u4*4v5*4=6,561u16v20 lets try another one (8x5y4)2 to solve it we seperate them we get (8x5y4)2=(8)2(x5)2(y4)2=64x5*2y4*2=64x10y8 lets try the last one (3p3s4h8d2a6)6 to solve it we seperate them we get (3p3s4h8d2a6)6=(3)6(p3)6(s4)6(h8)6(d2)6(a6)6=729p3*6s4*6h8*6d2*6a6*6=729p18s24h48d12a36
