Question

ДАЮ 35 БАЛЛОВ!! Пожалуйста помогите, с решением

Answer 1

1) 1

2) 4

3) 3

4) 1

5) 2

$4 {}^{ - 3} = \frac{1}{4 {}^{3} } = \frac{1}{64}$

$54 \times 3 {}^{ - 3} =54 \times \frac{1}{ {3}^{3} } = 54 \times \frac{1}{27} = \frac{54}{27} = 2$

${a}^{ - 3} a {}^{ - 2} a {}^{8} = a {}^{8 - 3 - 2} = a {}^{8 - 5} = a {^3}$

$( {a}^{3} ) {}^{ - 6} = a {}^{3 \times ( - 6)} = a {}^{ - 18}$

$\frac{b {}^{3} }{b {}^{ - 4} } = b {}^{3 - ( - 4)} = b {}^{3 + 4} = b {}^{7}$
