Question

Please i need help with these

( please notice that on the first one there is squares those dont matter dont worry about them please)

Answer 1

1.
`(4)/(27)`

2. D

Explanation:

1.
`3^(-2) * 1 * 4^3 * 3^(-1)*4^{-2`

=
`3^(-3) * 4^1`

=
`(4^1)/(3^3)`

=
`(4)/(27)`

2. Remember the rule that 1/a^b is equal a^-b, in this case,
`(1)/(2^3)` is the same as
`2^(-3)`, now 6 + (-3) = 3 -- which will be the exponent.
`2^3` is correct.
