Question

Pleaseee someone help!!!! I’m sooo confused right now

Answer 1

Your friend made the mistake of adding the coefficents and multiplying the exponents (instead of mulitplying the coefficents and adding the exponents)

The correct answer is:
`12a^{(7)/(10)}`

Explanation:

When mulitiplying exponentials with the same base you mulitply their coefficents and add their exponents.

Your friend made the mistake of adding the coefficents and multiplying the exponents

Answer 2

Your friend made a mistake when multiplying the coefficients of each term and when adding the exponents of each term.

Correct answer:
`\left(12a\right)^(7/10)`

Explanation:

We can use the exponent property
`a^b\cdot a^c=a^((b+c))` to solve this problem.

Substituting given values, we get:

`4a^{((1)/(2))}\cdot 3a^{((1)/(5))}=12a^{((1)/(2)+(1)/(5))}=12a^{((5)/(10)+(2)/(10))}=\boxed{12a^{((7)/(10))}}`
