Q. Simplify.Remove all perfect squares from inside the square roots. Assume x and z are positive.72x3z3 =
Factorize the expression: Factorize the expression inside the square root to identify perfect squares.We need to factorize 72x3z3 to find perfect squares. The prime factorization of 72 is 23×32. So, we can write 72x3z3 as (23×32×x3×z3).
Group the factors into perfect squares: Group the factors into perfect squares.We can group the factors as follows: (22⋅2)⋅(32)⋅(x2⋅x)⋅(z2⋅z). Here, 22, 32, x2, and z2 are perfect squares.
Take the square root of the expression: Take the square root of the expression, separating the perfect squares from the non-perfect squares.The square root of the expression becomes 22⋅32⋅x2⋅z2⋅2⋅x⋅z.
Simplify the square root of the perfect squares: Simplify the square root of the perfect squares and leave the rest inside the square root.Since the square root of a perfect square is just the base of the square, we get 2×3×x×z×2×x×z.
Combine the coefficients and simplify the expression: Combine the coefficients and simplify the expression.The final simplified expression is 6xz×2xz.
