Jawaban:

$sqrt{ {3}^{x - 5} } = 1 \ 3 {}^{ frac{x - 5}{2} } = {3}^{0} \ frac{x - 5}{2} = 0 \ x - 5 = 0 times 2 \ x - 5 = 0 \ x = 5$

$sqrt{3 {}^{ : 2x + 1} } = {9}^{x - 2} \ {3}^{ frac{2x + 1}{2} } = {3}^{2x - 4} \ frac{2x + 1}{2} = 2x - 4 \ 2x + 1 = 4x - 8 \ 2x - 4x = - 8 - 1 \ - 2x = - 9 \ x = frac{9}{2}$
