Solve -1.8-5^5+-5^6-(3.6*-5)+2-5^2-1.8+(-5)

$$-1.8 { -5 }^{ 5 } + { -5 }^{ 6 } -(3.6 \times -5)+2 { -5 }^{ 2 } -1.8+(-5)$$

Evaluate

$$21311.2$$

Solution Steps

Calculate -5 to the power of 5 and get -3125.

$$-1.8\left(-3125\right)+\left(-5\right)^{6}-3.6\left(-5\right)+2\left(-5\right)^{2}-1.8-5$$

Multiply -1.8 and -3125 to get 5625.

$$5625+\left(-5\right)^{6}-3.6\left(-5\right)+2\left(-5\right)^{2}-1.8-5$$

Calculate -5 to the power of 6 and get 15625.

$$5625+15625-3.6\left(-5\right)+2\left(-5\right)^{2}-1.8-5$$

Add 5625 and 15625 to get 21250.

$$21250-3.6\left(-5\right)+2\left(-5\right)^{2}-1.8-5$$

Multiply 3.6 and -5 to get -18.

$$21250-\left(-18\right)+2\left(-5\right)^{2}-1.8-5$$

The opposite of -18 is 18.

$$21250+18+2\left(-5\right)^{2}-1.8-5$$

Add 21250 and 18 to get 21268.

$$21268+2\left(-5\right)^{2}-1.8-5$$

Calculate -5 to the power of 2 and get 25.

$$21268+2\times 25-1.8-5$$

Multiply 2 and 25 to get 50.

$$21268+50-1.8-5$$

Add 21268 and 50 to get 21318.

$$21318-1.8-5$$

Subtract 1.8 from 21318 to get 21316.2.

$$21316.2-5$$

Subtract 5 from 21316.2 to get 21311.2.

$$21311.2$$

Factor

$$\frac{17 \cdot 1567 \cdot 2 ^ {2}}{5} = 21311\frac{1}{5} = 21311.2$$
