Question

Heeelllllllllllp Simplify the expression completely.
√144 +18 √12-5√64

Answer 1

A

Explanation:

using the rule of radicals

`√(a)` ×
`√(b)` ⇔
`√(ab)` , then

`√(12)`

=
`√(4(3))`

=
`√(4)` ×
`√(3)`

= 2
`√(3)`

Then

`√(144)` + 18
`√(12)` - 5
`√(64)`

= 12 + 18(2
`√(3)` ) - 5(8)

= 12 + 36
`√(3)` - 40

= - 28 + 36
`√(3)`
