Given :

Expression given as : (\frac{2}{5})^{2x-2}=\frac{32}{3125}

To Find :

Value of x.

Solution:

(\frac{2}{5})^{2x-2}=\frac{32}{3125}

(\frac{2}{5})^{2x-2}=\frac{2^5}{5^5}

(\frac{2}{5})^{2x-2}=(\frac{2}{5})^5

By equating exponents of both the sides of the expression,

(2x - 2) = 5

2x = 5 + 2

x = \frac{7}{2}

x = 3.5
