Question

How do I do this question about indices?

Answer 1

`(b^(4) )/(a^(2) )`

using the ' laws of exponents '

`(a^(m) )/(a^(n) )` =
`a^(m - n))` if m > n and

`a^(( n - m ))` if n > m

=
`(b^(( 6 - 2 )) )/(a^(( 3 - 1 ))  )` =
`(b^(4) )/(a^(2) )`

Answer 2

The answer is b^4/a^2

You would subtract the 6 on the top by the 2 on the bottom to help reduce the "B" and then subtract one from the top from the 3 from the bottom as well to again help reduce.
