Question

$$(-30+ { 2 }^{ 3 } )-[(-5)+5 \sqrt{ 1 } -5]-(-3) \times (-7)$$

Evaluate

$-38$

Solution Steps

Calculate $2$ to the power of $3$ and get $8$.

$$-30+8-\left(-5+5\sqrt{1}-5\right)-\left(-3\left(-7\right)\right)$$

Add $-30$ and $8$ to get $-22$.

$$-22-\left(-5+5\sqrt{1}-5\right)-\left(-3\left(-7\right)\right)$$

Calculate the square root of $1$ and get $1$.

$$-22-\left(-5+5\times 1-5\right)-\left(-3\left(-7\right)\right)$$

Multiply $5$ and $1$ to get $5$.

$$-22-\left(-5+5-5\right)-\left(-3\left(-7\right)\right)$$

Add $-5$ and $5$ to get $0$.

$$-22-\left(-5\right)-\left(-3\left(-7\right)\right)$$

The opposite of $-5$ is $5$.

$$-22+5-\left(-3\left(-7\right)\right)$$

Add $-22$ and $5$ to get $-17$.

$$-17-\left(-3\left(-7\right)\right)$$

Multiply $-3$ and $-7$ to get $21$.

$$-17-21$$

Subtract $21$ from $-17$ to get $-38$.

$$-38$$

Factor

$-38$
