Which expression is not equivalent to

Answer:
A
Step-by-step explanation:
Because 6^3/6^6 is equivalent to 1/216.A is 1/36
Answer:
Option A, 1/6² is not equivalent to the expression
Step-by-step explanation:
Lets simplify the given expression first:
[tex]\frac{6^3}{6^6}[/tex] = [tex]\frac{216}{46656}[/tex] which simplifies to; [tex]\frac{1}{216}[/tex]
Now let's see why the first equation is not equal to the simplified expression:
As noticed all the expressions are congruent to the given expression BUT expression given in the first option, therefore they are not equal.
Hope this helps!
