Question

How do I do this question about indices?

Answer 1

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.

Answer 2

$\frac{b^{4} }{a^{2} }$

using the ' laws of exponents '

$\frac{a^{m} }{a^{n} }$ = $a^{m - n)}$ if m > n and

$a^{( n - m )}$ if n > m

= $\frac{b^{( 6 - 2 )} }{a^{( 3 - 1 )}  }$ = $\frac{b^{4} }{a^{2} }$
