Solve -2^3+-81/3=

$$- { 2 }^{ 3 } + -8 \frac { 1 } { 3 } =$$

Evaluate

$$-\frac{49}{3}\approx -16.333333333$$

Solution Steps

Calculate 2 to the power of 3 and get 8.

$$-8-\frac{8\times 3+1}{3}$$

Multiply 8 and 3 to get 24.

$$-8-\frac{24+1}{3}$$

Add 24 and 1 to get 25.

$$-8-\frac{25}{3}$$

Convert -8 to fraction -\frac{24}{3}.

$$-\frac{24}{3}-\frac{25}{3}$$

Since -\frac{24}{3} and \frac{25}{3} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-24-25}{3}$$

Subtract 25 from -24 to get -49.

$$-\frac{49}{3}$$

Factor

$$-\frac{49}{3} = -16\frac{1}{3} = -16.333333333333332$$
