Answer 1

Answer:-

Given :

${5}^{n} - {5}^{n - 2} = \frac{k}{25} \times {5}^{n}$

And,

k = 15 + x.

$→{5}^{n} ( {5}^{0} - {5}^{ - 2} ) = \frac{15 + x( {5}^{n} )}{25} \\ \\→ 1 - \frac{1}{25} = \frac{x + 15}{25} \\ \\ → \frac{25 - 1}{25} = \frac{x + 15}{25}$

(25 is being cancelled out both sides).

$→24 = x + 15 \\ \\→ 24 - 15 = x \\ \\→ x = 9.$

Hence, the value of x is 9.
