Solve {left(21^/3right)}^2

$${ \left( 2 \frac { { 1 }^{ } } { 3 } \right) }^{ 2 }$$

Evaluate

$$\frac{4}{9}\approx 0.444444444$$

Solution Steps

Calculate 1 to the power of 1 and get 1.

$$\left(2\times \frac{1}{3}\right)^{2}$$

Multiply 2 and \frac{1}{3} to get \frac{2}{3}.

$$\left(\frac{2}{3}\right)^{2}$$

Calculate \frac{2}{3} to the power of 2 and get \frac{4}{9}.

$$\frac{4}{9}$$

Factor

$$\frac{2 ^ {2}}{3 ^ {2}} = 0.4444444444444444$$
