Answer:
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
Step-by-step explanation:
9x = 120
x=
S56=56/2[2(-8)+(56-1)7]
S56=10332
210
because you use 13.% divided by the price
2
the biggest number they can both divide by is 2.
