Answer 2

Answer:

The value of x is -1.

Step-by-step explanation:

Exponents rule:

• $a^{m}\times a^{n}=a^{m+n}$
• If $a^{m}=a^{n}$ then m = n.

Solve for x as follows:

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

Thus, the value of x is -1.
