2. 1. sqrt 18 = sqrt (9x2) = sqrt (3^2)x 2 = 3 sqrt 2
2. sqrt 12 = sqrt (4x3) = sqrt (2^2)x3 = 2 sqrt 3
3. cubert 40 = cubert (8x5) = cubert (2^3)x5 = 2 cubert 5

Please do the remaining questions accordingly.

3. Hello, markie_ien!

Do you know how to simplify radicals?

For example, for square roots

. . $\sqrt{ab}\:=\:\sqrt{a}\cdot\sqrt{b}$

In baby-talk, if we have the square root of a product,
. . we can "split" them into two square roots.

Example: Simplify $\sqrt{18}$

We know that 18 is not a square number.

Can we factor it so that one factor is a square?
. . Yes: . $18 \:=\:9 \times 2$

So we have: . $\sqrt{18}\:=\:\sqrt{9\cdot2} \:=\:\sqrt{9}\cdot\sqrt{2}$

Since $\sqrt{9} = 3$, the answer is: . $3\sqrt{2}$

Now try this on the problems with square roots . . .
