    sqrt(3a)+16asqrt(3a)===>17sqrt(3a)

    sqrt(3a)+8sqrt(12a^(3)) Pull all perfect square roots out from under the radical. In this case, remove the 2a because it is a perfect square. sqrt(3a)+(8*2asqrt(3a)) Multiply 8 by 2a to get 16a. sqrt(3a)+(16a)sqrt(3a) Remove the parentheses around the expression 16a. sqrt(3a)+16asqrt(3a)

    the a goes before the root not after it

    the answer is \[\Huge \sqrt{3a}(16a+1)\]

    so if it's the right answer, there could never be an extra a, if there was it would be one a too many and it would be wrong

    Yes, you're right, you can't add them...so factoring out the sqrt(3a) was a good step....
