Introduction to Radicals

Adding and Subtracting Radical Expressions

Directions:

Simplify the below radical expression by combining 'like' terms.

$2 \sqrt{32} + 5 \sqrt{18} - 3 \sqrt{8}$

	Simplify the first term: $2 \sqrt{32}$
	$\sqrt{2} + 5 \sqrt{18} - 3 \sqrt{8}$
	Simplify the second term:
	$8 \sqrt{2} + \sqrt{2} - 3 \sqrt{8}$
	Simplify the third term:
	$8 \sqrt{2} + 15 \sqrt{2} - \sqrt{2}$
	Combine terms:
	$\sqrt{2}$

Note: During development, the is not yet functioning. Use the 'v' key to begin the number undr the radicand and also the 'v' key again to end the number onder the radicans. Example: 17 wopuld be typed in as v17v.

Your simplified expression:

8 \sqrt{2} + 15 \sqrt{2} - 6 \sqrt{2} = 17 \sqrt{2}

Congratulations! you provided the correct answer:
$8 \sqrt{2} + 15 \sqrt{2} - 6 \sqrt{2} = 17 \sqrt{2}$
