Hhhhhhheeeeeeeeeeeeeelllllllllp​

Answer 1

1/5^9

Explanation:

5^-6 goes down and become 5^6

then 5^3 is times 5^6, when multiplying two same bases their power has to be added not multiplied. so 6 plus 3 is 9. the nine is the power.

the final answer is 1/5^9 or the first choice

Answer 2

It's A, 1/5^9.

Ya take the two exponents, and subtract them. Now ya have 5^-9/5.

Since we can't have a negative exponent, we put it on the bottom.

So we get the answer 1/5^9. Hope this helps!
