3/ (x^3a+1)(x^a-3)/4sqrtx^8
Thanks alot
What did you do there for 1, I am assuming you just wrote the second question as the first by mistake. For 3,
For 2 how did you get y^8 and not y^16, can you show steps please?
in the numerator it is x^{3a+1} and x^{a-3}
and if you don't mind me asking how do i simplify (27)^-2/3
William,
Do you know that ?
That's what I used to answer the first one. You could also look at it this way:
. You can convert this into rational exponents by dividing the power in the radicand by the index of the root.
Or, you could expand the radicand first and then simplify at the end like
