Write in exponential form and simplify. ^3sqrt(a) * ^5sqrt(a)
I am not sure what you mean by the symbol ^, we use this symbol to express the power, but in your question there is no base . So I will assume the following:
3sqrt(a) * 5sqrt(a)
Multiply integers together and square roots together.
= (3*5)* (sqrt(a)*sqrt(a))
= 15 (a)
= 15 a
