Question

(4 to the power x - 2)-(2 to the power x+1)=o ;solve for x​

Answer 1

${4}^{(x - 2)} - {2}^{(x + 1)} = 0 \\ \\ {4}^{(x - 2)} = {2}^{(x + 1)} \\ \\ { ({2}^{2}) }^{(x - 2)} = {2}^{(x + 1)} \\ \\ {2}^{2(x - 2)} = {2}^{(x + 1)} \\ \\ as \: base \: are \: same \: comparing \: both \: sides \: \\ \\ 2(x - 2) = x + 1 \\ \\ 2x - 2 = x + 1 \\ \\ 2x - x = 1 + 2 \\ \\ x = 3$
