Answer 1

${2}^{8} \times {2}^{6} = {2}^{14} \\ {2}^{8} \div {2}^{6} = {2}^{2} \\ {3}^{3} = 3 \times 3 \times 3 = 27 \\ ( {2}^{3} {)}^{6} = {2}^{18}$

${2}^{8} = 256 \\ {2}^{ - 3} = \frac{1}{8}$

$( \frac{1}{2} {)}^{ - 2} = 4 \\ \\ {7}^{0} = 1 \\ \\ ( \frac{5}{2}) {}^{ - 3} = \frac{8}{125}$

${5}^{3} = 125 \\ 5 {}^{ - 3} = \frac{1}{125} .$
