Question

1. -12sqrt(30)/3sqrt(6)
think its 4sqrt(5)

2. sqrt(32x^3 y^5)/(-5sqrt(xy))
think is its 4xy^2/5

3. 3sqrt(m^5)+5sqrt(m^3)
think its 5m^2 + 3m

4. sqrt(x^3y^2)/sqrt(9x^7)
think its y^2 / 3x^2

Answer 1

Radical formula is √(ab) = √a√b

Answer 2

2).

This expression it can be written as

Radical rules: If n is odd then n^th√aⁿ = a and √(ab) = √a√b

.

Answer 3

This expression it can be written as

Radical rules: If n is odd then n^th√aⁿ = a and √(ab) = √a√b

Take out common term √m.

Answer 4

This expression it can be written as

Radical rules: If n is odd then n^th√aⁿ = a and √(ab) = √a√b
