Question

How do you simplify `(-2jk^7)^4`?

Answer 1

`=color(blue)(16j^4k^28`

Explanation:

`(−2jk^color(blue)(7))^color(blue)(4`

By property :

`color(blue)((a^m))^n= color(blue)(a^(mn`

Applying the same:

`(−2jk^color(blue)(7))^color(blue)(4 )= -2^color(blue)(4)*j^color(blue)(4) *k^color(blue)((7*4)`

`=color(blue)(16j^4k^28`
