Look at this equation: m^3 = 27 What is m, the cube root of 27? m = ____

Recognize Cube Expression: Recognize that 27 can be expressed as a cube of a number. 27 = 3 * 3 * 3 27 = 3^3Apply Cube Root: Apply the cube root to both sides of the equation m^3 = 27 to solve for m. m = cube root of 27 m = cube root of (3^3) Since the cube root and cube power cancel each other, m = 3.

Recognize Cube Expression: Recognize that $27$ can be expressed as a cube of a number. $\newline$ $27 = 3 \times 3 \times 3$ $\newline$ $27 = 3^3$
Apply Cube Root: Apply the cube root to both sides of the equation $m^3 = 27$ to solve for $m$ . $\newline$ $m = \text{cube root of } 27$ $\newline$ $m = \text{cube root of } (3^3)$ $\newline$ Since the cube root and cube power cancel each other, $m = 3$ .
