11-27.

Rewrite each of the following equations in $y = ab^{x}$ form.

$y = 16(2)^{2x-2}$
Step (a):
$y=16\cdot 2^{2x}\cdot 2^{-2}$

$y = ( 4 ) ^ { \frac { 1 } { 2 } x + 2 }$
Step (b):
$y= (4^{1/2})^x\cdot 4^2$

$y = 60( \frac { 1 } { 2 } ) ^ { 3 x + 1 }$
Step (c):
$y=60\left(\frac{1}{2}\right)^{3x}\left(\frac{1}{2}\right)^1$

$y = 81( \frac { 4 } { 9 } ) ^ { \frac { 1 } { 2 } x + 2 }$
Step (d):
$81\left(\left(\frac{4}{9}\right)^{1/2}\right)^x\left(\frac{4}{9}\right)$
