Срочно!! Пж!!!!!! !!!!!!!!!!!!

Answer 1

Пошаговое объяснение:

1. а)

${4}^{2} = 16$

б)

${6}^{ - 2} = \frac{1}{36}$

в)

${2}^{ - 6} = \frac{1}{64}$

2. а)

${x}^{ - 12} \times x ^{14 } \\ {x}^{2}$

б)

$6 {a}^{ - 1} \times b \\ \frac{6b}{a}$

3. а)

$( \frac{1}{3} \times \frac{1}{x} \times {y}^{2} ) ^{ - 2} \\ ( \frac{3x}{y ^{2} } ) ^{2} \\ \\ \frac{ {9x}^{2} }{ {y}^{4} }$

б)

$\frac{ {4y}^{ - 3} }{ {3x}^{ - 1} } \times {6xy}^{2} = {4y}^{ - 3} \times {2x}^{2} {y}^{2} = {8x}^{2} {y}^{1} = \frac{ {8x}^{2} }{y}$

4.

$\frac{ {3}^{ - 9} \times {3}^{ - 8} }{ {3}^{ - 18} } = {3}^{9} \times {3}^{ - 8} = 3$
