Question

Heelp me pls......


simplify each radical, then add or subtract. sqrt12 +sqrt27​

Answer 1

`5√(3)`

Explanation:

simplify sqrt(12):
`√(12) = √(4 * 3) = √(4) * √(3) = 2 * √(3) = 2√(3)`

simplify sqrt(27):
`√(27) = √(9 * 3) = √(9) * √(3) = 3 * √(3) = 3√(3)`

substitute into original equation:
`√(12) + √(27) = 2√(3) + 3√(3)`

factor out sqrt(3):
`√(3) * (2 + 3)`

simplify:
`√(3) * 5 = 5√(3)`
