Alg 1 Test 10 - Laws of Exponents

Whenever we see exponents and it is multiple choice, we can use the ​ (a)   and the strategy ​ ​ (b)   .

Whenever we see exponents and it is NOT multiple choice, we have to use the ​ (c)   and the ​ (d)  

Label each part of the formula correctly

Match the following:

$$x^0$$ = ​ (a)   $$y^0$$ =​ (b)   $$0^0$$ =​ (c)   $$any\ number^0$$ =​ (d)  

Match each negative exponent to its correct value.
