Question

Simplify (16x^12)^3/4

Answer 1

I'd rewrite 16 as 2^4

and the index law you need is power of a power

\[(x^a)^b = x^{a \times b}\]

so in your question your have

\[(2^4x^{12})^{\frac{3}{4}} = (2^4)^{\frac{3}{4}} \times (x^{12})^{\frac{3}{4}}\]

multiply the powers for the solution..

you may need to wwrite your power of 2 as a normal number

Answer 2

So 8x^9

Answer 3

thats correct

Answer 4

Thanx:-)
