Answer 2

$\boxed{ \huge \bf \green{a {}^{x} \times a {}^{y} = a {}^{x + y} }}$

a)

$\bf( \frac{3}{2} ) {}^{7} \times ( \frac{3}{2} ) {}^{15} = ( \frac{3}{2} ) {}^{7 + 15} =( \frac{3}{2} ) {}^{22}$

b)

$\bf( \frac{7}{3} ) {}^{8} \times ( \frac{7}{3} ) {}^{11} = (\frac{7}{3} ) {}^{8 + 11} = (\frac{7}{3} ) {}^{19}$

c)

$\bf( \frac{2}{5} ) {}^{6} \times ( \frac{2}{5} ) {}^{19} = ( \frac{2}{5} ) {}^{6 + 19} = ( \frac{2}{5} ) {}^{25}$
