(4a^-2)^4

(9ab^-5)^-2

Sagot :

The simplified expression are as follows:

[tex](24m^{-2}n )(\frac{1}{4}mn ) =6m^{-1} n^{2}[/tex]

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

[tex](9ab^{-5} )^{-2} =9ab^{10}[/tex]

How to simplify an expression?

The expression can be simplified as follows;

using law of indices,

[tex](a^{x} )^{y} = a^{xy}[/tex]

Therefore,

[tex](24m^{-2}n )(\frac{1}{4}mn ) = \frac{24}{4} m^{-2+1} n^{1+1} =6m^{-1} n^{2}[/tex]

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

[tex](9ab^{-5} )^{-2} =9ab^{10}[/tex]
