Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• If ${5}^{x} \times {5}^{x + 5} = {5}^{20}$, find the value of x.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

${5}^{x} \times {5}^{x + 5} = {5}^{20}$

$\implies {5}^{x + x + 5} = {5}^{20}$

$\implies {5}^{2x + 5} = {5}^{20}$

Comparing base, we get,

$2x + 5 = 20$

$\implies2x = 15$

$\implies x = \frac{15}{2}$

$\implies x = 7.5$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• The value of x is 7.5
