Solve 33^2-21/33

$$3 { 3 }^{ 2 } -2 \frac{ 1 }{ 3 } 3$$

Evaluate

$$20$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

$$3^{3}-\frac{2\times 3+1}{3}\times 3$$

Calculate 3 to the power of 3 and get 27.

$$27-\frac{2\times 3+1}{3}\times 3$$

Multiply 2 and 3 to get 6.

$$27-\frac{6+1}{3}\times 3$$

Add 6 and 1 to get 7.

$$27-\frac{7}{3}\times 3$$

Cancel out 3 and 3.

$$27-7$$

Subtract 7 from 27 to get 20.

$$20$$

Factor

$$2^{2}\times 5$$
