"Addition of radicals:

√18 + √32

Factor numbers to get one perfect square

= √9(2) + √16(2)

= 3√2 + 4√2

= 7√2

Subtraction of radicals:

√18 - √32

Factor numbers to get one perfect square

= √9(2) - √16(2)

= 3√2 - 4√2

= -√2

Multiplication of radicals:

√18 (√32)

Factor numbers to get one perfect square

= (√9(2))(√16(2))

= (3√2)(4√2)

= 12(2)

= 24

Division of radicals:

√18 ÷ (√32)

Factor numbers to get one perfect square:

√9(2) ÷ √16(2)

= 3√2 ÷ 4√2

Cancel out √2

= 3/4"
