 (am)n\left(a^m\right)^n   je izraz koji se zove stepen stepena

3

Na primer:

  •  (24)3=242424=24+4+4=212\left(2^4\right)^3=2^4\cdot2^4\cdot2^4=2^{4+4+4}=2^{12}  

  •  (37)5=3737373737=335\left(3^7\right)^5=3^7\cdot3^7\cdot3^7\cdot3^7\cdot3^7=3^{35}  

4

 (am)n=amn\left(a^m\right)^n=a^{m\cdot n}

Fill in the Blanks

 57(53)259=5\frac{5^7\cdot\left(5^3\right)^2}{5^9}=5^{\nabla}  

Umesto trougla treba da stoji broj 




Type answer...

Fill in the Blanks

 a30:((a3)2(a2)5)=aa^{30}:\left(\left(a^3\right)^2\cdot\left(a^2\right)^5\right)=a^{\nabla}  Umesto trougla treba da stoji broj:

  \   Izračunaj

 3298275\frac{3^2\cdot9^8}{27^5}  

Kako je 9=329=3^2  i  27=3327=3^3   naš izraz ima vrednost

 32(32)8(33)5=32316315=318315=33=27\frac{3^2\cdot\left(3^2\right)^8}{\left(3^3\right)^5}=\frac{3^2\cdot3^{16}}{3^{15}}=\frac{3^{18}}{3^{15}}=3^3=27
