Question

3. What is the simplified form of 4 V3 – V27?

Answer 1

Answer:

C

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplify $\sqrt{27}$

= $\sqrt{9(3)}$

= $\sqrt{9}$ × $\sqrt{3}$

= 3$\sqrt{3}$

Then

4$\sqrt{3}$ - 3$\sqrt{3}$

= $\sqrt{3}$ → C
