Answer:
6²
Step-by-step explanation:
a fraction means dividing the numerator by the denominator (the top number by the bottom number) so you do 6⁷÷6⁵ but when dividing by powers, you simply subtract them. this means 6⁷÷6⁵=6² because 7-5=2
you DONT calculate that 6²=36 in this equation because the question tells you to keep your answer in index form so you have ti answer it with 6²
