Question

What's the geometric mean of 13 and 17?

Answer 1

x^-m=1/x^m

1/12=12^-1

also

(x^m)^n=x^(mn)

also (x^m)(x^n)=x^(m+n)

( \frac{1}{12} )^{-2b}(12)^{-2b+2}=12

( 12^{-1})^{-2b}(12)^{-2b+2}=12

( 12^{2b})(12)^{-2b+2}=12

12^{2b-2b+2}=12

12²=12

false

no solution

Explanation:

Answer 2

`√(13*17)=11`
