Question

Simplify the expression. a^-5 b-4/a^-13 b^8​

Answer 1

a^8 ÷ b^12

Explanation:

a^-5 · b^-4 / a^-13 · b^8

when dividing exponents with the same bases, subtract the exponents

a^8 · b^-12

do not leave a negative exponent; put it into the denominator and it becomes positive

b^-12 = 1 /b^12
