Radicals Practice (Algebra)

Simplify the following: 4√5 - 6√5 + 4√3 - 2√3

• 3√5 - 4√5 + 4√3 - 2√3
• -2√5 + 2√3
• √3
• 10√5 + 2√3

√5 × √10

• 50
• 2√5
• 5√2
• 5√10

Solve by taking square roots:

5m² + 1 = 6

• m = 1

• m = -1

• m = √7

• m = 7/5 m = -7/5

Solve using square roots.

k² - 6 = 43

• k = √37

• k = 37 or - 37

• k = 7

• no real solution
