Question

X 9. Find x so that (3/5) power3 (3/5)power6 = (3/5)Power 2x-1.​

Answer 1

Step-by-step explanation:

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