Answer 1

Ответ:

${x}^{2} \times {x}^{5} = {x}^{2 + 5} = {x}^{7}$

${a}^{4} \div {a}^{6} = {a}^{4 - 6} = {a}^{ - 2} = \frac{1}{a ^{2} }$

${( {m}^{5}) }^{2} = {m}^{5 \times 2} = {m}^{10}$

${2}^{4} + 1 = 16 + 1 = 17$

${3}^{3} \times 2 = 27 \times 2 = 54$

$( {5}^{2} - 9)( {9}^{2} - 5) = (25 - 9)(81 - 5) = 16 \times 76 = 1216$
