Question

find x so that (3/5) of power 3 *(3/5) of power 6 = 3/5 of power 2x-1​

Answer 1

Answer:

$({ \frac{3}{5} )}^{3} \times ( { \frac{3}{5} )}^{6} = ({ \frac{3}{5}) }^{2x - 1} \\ ({ \frac{3}{5} )}^{3 + 6} = { \frac{3}{5} }^{2x - 1} \\ { \frac{3}{5} }^{9} = { \frac{3}{5} }^{2x - 1} \\ 9 = 2x - 1 \\ 9 + 1 = 2x \\ 10= 2x \\ 5 = x$
