Question

36 :[2^ -2 +2^ -3 +3^ -2 ]

Answer 1

$36 \div [2^{-2} +2^{-3}+2^{-2} ]$

$36 \div [\frac{1}{2^2}+\frac{1}{2^3}+\frac{1}{2^2} ]$

$36 \div [\frac{1}{4} +\frac{1}{8} +\frac{1}{4}]$

$36 \div [\frac{1+1}{4}+\frac{1}{8}]$

$36 \div [\frac{2}{4}+\frac{1}{8} ]$

$36 \div [\frac{1}{2}+\frac{1}{8}]$

$36 \div [\frac{4+1}{8} ]$

$36 \div \frac{5}{8}$

$36 \times \frac{8}{5}$

$\frac{36 \times 8}{5}$

$\frac{288}{5}=57,6$
