Question

How do you use laws of exponents to simplify `y^(2a) * y^3 * y^(3a+1)`?

Answer 1

I got: `y^(5a+4)`

Explanation:

Remember that you have:
`y^a*y^b=y^(a+b)`

for example if you have:
`2^2*2^3=2^(2+3)=2^5=32`
in fact:
`2^2=4`
`2^3=8` and
`4*8=32`!!!
So, in your case you have:
`y^(2a+3+3a+1)=y^(5a+4)`
