Introduction to Radicals

Adding and Subtracting Radical Expressions

Directions:

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

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

Hint: Remove all perfect square factors before adding and subtracting like radicals. Don't forget the signs!

	Simplify the first term: $2 \sqrt{32}$	Your solution:
	$+ 5 \sqrt{18} - 3 \sqrt{8}$

	Simplify the second term:	Your solution:
	$2 \sqrt{32} - 3 \sqrt{8}$

	Simplify the third term:	Your solution:
	$2 \sqrt{32} + 5 \sqrt{18}$

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