Question

essa fração (13-1)²:[√64:2³+(81:3²-8).3]+6² passo a passo por favor to precisando mt pra amanha

Answer 1

$\frac{(13-1)^2}{[ \sqrt{64}:2^3+(81:3^2-8)\cdot3]}+6 \\ \\= \frac{12^2}{[8:8+(81:9-8)\cdot3]}+6 \\ \\= \frac{144}{[1+(9-8)\cdot3]}+6 \\ \\ =\frac{144}{[1+1\cdot3]}+6 \\ \\ =\frac{144}{[1+3]}+6 \\ \\ =\frac{144}{4}+6 \\ \\ =36+6 \\ =42$
