10-97.

Using the properties of exponents, solve for A in each of the following equations.

1. $\frac { 1 } { 25 } · 5^{(x + 4)} = A · 5x$

$5^{-2}\cdot 5^{x+4}=A\cdot 5^x$

1. $16 · 2^{(x+4)} = A · 2x$

Follow the same thinking process as in (a).

1. $\frac { 1 } { 3 }· 3^{(x − 2)} = A · 3x$

Follow the same thinking process as in (a).
