Question

I really need help with this pls!

Nakim Simplified 3√2x + x√8x - 5√18x and got -10x√2x for an answer.

Part 1: Using complete sentences, explain what Nakim did wrong.

Part 2: Show all your work to simplify the expression.

(You can use "sqrt()" to show a square root. For example,7Part 1: Using complete sentences, explain what Nakim did wrong.

Part 2: Show all your work to simplify the expression.

(You can use "sqrt()" to show a square root. For example,
7√a can be written as 7sqrt(a). a can be written as 7sqrt(a). )

Answer 1

the answer to this equation is -12√2x+2x√2x

Answer 2

But what did Nakim do wrong?

Answer 3

a lot of things it seems

Answer 4

Explain

Answer 5

Nakim needs to be spanked

Answer 6

could be a number of things he did wrong, but i can't think what he did that would've led to that wrong answer

Answer 7

I need to know at least 1 thing that Nakim did wrong. That is part 1

Answer 8

the only thing i can think of is him bringing out the x in 3sqrt(2x) and -5sqrt(18x) which would give him -12xsqrt(2x) + 2xsqrt(2x) = -10xsqrt(2x)
But this doesn't sound logical because he didn't take out any x term in xsqrt(8x)

Answer 9

That is great! Thx so much mate!

Answer 10

no problem
