Question

Which is the value of this expression when m = 3 and n = -5?

Answer 1

The answer is:  [C]:  " 1/8 " .
_________________________________________________

(6 * 3⁻¹) ⁻³ =  (6 / 3¹) ⁻³ = 2⁻³ = 1 / 2³ = 1/8 ; which is answer choice:  [C]:


Note that n⁰ =1 ;  regardless  of what "n" is equal to;
                          and any value, multiplied by "1", equals that same value.

so "n⁰ " ; which equals "1" ; is simply "canceled out" .
