4^-3a^-5/16^-1a^-7, Write Expression With Positive Exponents

4^-3a^-5/16^-1a^-7
write expression with positive exponents

(The solution is in the picture)

Whenever there is a negative exponent all you have to do is change its position for example the

16¯¹ and a¯7 they are denominators but since both of them have a negative exponent then we will change its position to numerators so that it will become positive

Same goes at 4¯³ and a¯5 they are numerators but i change its position to denominators and the exponent sign changes to positive

And now just simplify it

The answer will be

a²/4

But if you dont want to simplify it yet and what you only need is that to transform the given expression without the negative exponents then the answer would be the no. 1 option
