Question

Which expression is not equivalent to 6^3/6^6? 1)1/6^2 2)6^-3 3)1/216 4)1/6^3

Answer 1

Remember
(x^m)/(x^n)=x^(m-n)
and
x^(-m)=1/(x^m)
so

(6^3)/(6^3)=6^(3-6)=6^-3=1/(6^3)
first one is wrong
2nd is right
3rdone is right
4th is right


first one is wrong 1/(6^2)

Answer 2

A) 1/6^2=6^-2


B) 6^-3


C) 1/216=1/6^3=6^-3


D) 1/6^3=6^-3
