Which of the following expression is equivalent to

Answer:
C
Step-by-step explanation:
No, the answer is C because when you raise a number to a negative exponent it is equivalent to one over the number to the same exponent, but positive. So, [tex]6^{-7} = \frac{1}{6^{7}}[/tex] and not [tex]\frac{1}{6^{-7}}[/tex].
