Solve 5(5.1^2)-4-5(5^2)-4

$$5( { 5.1 }^{ 2 } )-4-5( { 5 }^{ 2 } )-4$$

Evaluate

$$-2.95$$

Solution Steps

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

$$5\times 5.1^{2}-4-5^{3}-4$$

Calculate 5.1 to the power of 2 and get 26.01.

$$5\times 26.01-4-5^{3}-4$$

Multiply 5 and 26.01 to get 130.05.

$$130.05-4-5^{3}-4$$

Subtract 4 from 130.05 to get 126.05.

$$126.05-5^{3}-4$$

Calculate 5 to the power of 3 and get 125.

$$126.05-125-4$$

Subtract 125 from 126.05 to get 1.05.

$$1.05-4$$

Subtract 4 from 1.05 to get -2.95.

$$-2.95$$

Factor

$$-2.95$$
