Q. Simplify. Assume m is greater than or equal to zero.27m4
Factor and Express:27m4First, let's factor the radicand into its prime factors and express m4 as a square of squares.27m4=3×3×3×m2×m2
Group and Simplify:3×3×3×m2×m2Now, group the identical factors and use the exponents to simplify the expression.3×3×3×m2×m2=33×(m2)2
Apply Product Property:33⋅(m2)2Apply the product property of radicals, which states that a⋅b=a⋅b.33⋅(m2)2=32⋅3⋅(m2)2
Simplify Square Roots:32×3×(m2)2Simplify the square roots where possible. Since 32 and (m2)2 are perfect squares, they simplify to 3 and m2, respectively.32×3×(m2)2=3×3×m2
Combine Constants and Variables:3×3×m2Combine the constants and variables outside the square root to get the final simplified form.3×3×m2=3m2×3
