Answer 2

Answer:

$\sqrt{27} +3\sqrt{12}$   = 9√3

Step-by-step explanation:

Required to find $\sqrt{27} +3\sqrt{12}$

Solution:

27 = 3x3x3

$\sqrt{27}$ = $\sqrt{3 X3X3}$ = $\sqrt{3^2 X 3}$ = 3√3

12 = 2x2x3

3$\sqrt{12}$ = 3$\sqrt{2X2X3}$ = 2$\sqrt{2^2 X3}$ = 3×2×√3 = 6√3

$\sqrt{27} +3\sqrt{12}$  = 3√3 + 6√3 = 9√3

∴  $\sqrt{27} +3\sqrt{12}$   = 9√3
