Solve 80^1-5^4div(-25)*(-3)-769^0=?

$$80 ^ { 1 } - 5 ^ { 4 } \div ( - 25 ) \times ( - 3 ) - 769 ^ { 0 } = ?$$

Evaluate

$$4$$

Solution Steps

Calculate 80 to the power of 1 and get 80.

$$80-\frac{5^{4}}{-25}\left(-3\right)-769^{0}$$

Calculate 5 to the power of 4 and get 625.

$$80-\frac{625}{-25}\left(-3\right)-769^{0}$$

Divide 625 by -25 to get -25.

$$80-\left(-25\left(-3\right)\right)-769^{0}$$

Multiply -25 and -3 to get 75.

$$80-75-769^{0}$$

Subtract 75 from 80 to get 5.

$$5-769^{0}$$

Calculate 769 to the power of 0 and get 1.

$$5-1$$

Subtract 1 from 5 to get 4.

$$4$$

Factor

$$2^{2}$$
