Yeah uh I have no idea how to do this Use exponent laws to simplify this :
9√(a^-5 b^2)

The answer is 9b / a^5/2 I just don't know how so please show steps! Thank you

9b /a^5/2

Step-by-step explanation:

9√(a^-5 b^2)

9 sqrt( a^ -5 b^2)

Rewriting sqrt as ^1/2

9 ( a^ -5 b^2)^1/2

9 ( a^ -5) ^1/2 ( b^2)^1/2

we know that  an exponent to an exponent means multiply

9 a^ (-5*1/2)  b^(2*1/2)

9 a^-5/2 b^1

9b a^ -5/2

We know that x^-y = 1/x^y

9b /a^5/2

i used to know how to do this in 7th but i forget easily
