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).
