Question

5^(2x-1)=0,4 × 2^(2x-1)​

Answer 1

${5}^{2x - 1} = 0.4 times {2}^{2x - 1 } \ 1 = frac{2}{5} times {2}^{2x - 1 } div {5}^{2x - 1} \ 1 = { frac{2}{5} }^{2x} \ 2x = 0 \ x = 0$

Answer 2

$5^{2x-1} =0,4*2^{2x-1}\\frac{5^{2x-1} }{2^{2x-1} }=frac{0,4*2^{2x-1} }{2^{2x-1}};2^{2x-1}neq0\\(frac{5}{2})^{2x-1}=frac{2}{5}\\(frac{5}{2})^{2x-1}=(frac{5}{2})^{-1}\\2x-1=-1\\2x=0\\x=0$
