Verified answer

Ответ:

1)

[tex]a \div a^{3} = \frac{1}{a ^{2} } [/tex]

2)

[tex]( \frac{1}{ {a}^{2} } )^{2} = \frac{1}{ {a}^{4} } [/tex]

3)

[tex] \frac{1}{ {a}^{4} } \times {a}^{8} = {a}^{4} [/tex]

4)

[tex]( {a}^{4} )^{ - 2} = \frac{1}{ {a}^{8} } [/tex]

5)

[tex] \frac{1}{ {a}^{8} } \times b^{8} = \frac{ {b}^{8} }{ {a}^{8} } [/tex]

6)

[tex] \frac{ {b}^{8} }{ {a}^{8} } \times {a}^{8} b = {b}^{9} [/tex]

7)

[tex] {b}^{9} \div {b}^{9} = 1[/tex]

8)

[tex]1 \times {a}^{1} = a[/tex]
