Question

3sqrt2x^3 + 4xsqrt8x

Answer 1

hmm..first ill ask you...where are you having difficulties with in there?

Answer 2

Understanding the whole concept. The teacher just gives the answer and doesnt explain the process

Answer 3

hmmm first thing you might wanna do is factor out the values inside of the square roots

Answer 4

ok

Answer 5

\[3\sqrt{2x^3} = 3\sqrt{2x \times x^2} = 3x \sqrt{2x}\]

\[4x \sqrt{8x} = 4x \times 2 \sqrt{2x}\]

so the problem is now

\[3x \sqrt{2x} + 8x \sqrt{2x} = 11x \sqrt{2x}\]
