remember
x^-m=1/x^m
1/12=12^-1
also
(x^m)^n=x^(mn)
also (x^m)(x^n)=x^(m+n)

[tex]( \frac{1}{12} )^{-2b}(12)^{-2b+2}=12[/tex]
[tex]( 12^{-1})^{-2b}(12)^{-2b+2}=12[/tex]
[tex]( 12^{2b})(12)^{-2b+2}=12[/tex]
[tex] 12^{2b-2b+2}=12[/tex]
12²=12

Solution:

(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

12^2 = 12

144 does not equal 12

No solution.

Best of Luck!
