Answer 1

Answer:

A. $(\frac{-7}{5} )^{11}$ ÷ $(\frac{-7}{5} )^{3}$ = $(\frac{-7}{5}) ^{2x+2}$

    $(\frac{-7}{5} )^{11-3}$ =  $(\frac{-7}{5}) ^{2x+2}$

    $(\frac{-7}{5}) ^{8\\}$ = $(\frac{-7}{5}) ^{2x+2}$

8 = 2x + 2

8 -2 = 2x

2x = 6

x = 6/2

x = 3

B.  $(\frac{3}{13})^{8+2} = (\frac{3}{13})^{10}$ = $(\frac{3}{10}) ^{a+1}$

10 = a + 1

a = 10-1

a = 9

Therefore,

x = 3

a = 9

Hope this helps!
