Solve 4(-3)(4)-5sqrt{3^2+4^2}

$$4 ( - 3 ) ( 4 ) - 5 \sqrt { 3 ^ { 2 } + 4 ^ { 2 } }$$

Evaluate

$$-73$$

Solution Steps

Multiply 4 and -3 to get -12.

$$-12\times 4-5\sqrt{3^{2}+4^{2}}$$

Multiply -12 and 4 to get -48.

$$-48-5\sqrt{3^{2}+4^{2}}$$

Calculate 3 to the power of 2 and get 9.

$$-48-5\sqrt{9+4^{2}}$$

Calculate 4 to the power of 2 and get 16.

$$-48-5\sqrt{9+16}$$

Add 9 and 16 to get 25.

$$-48-5\sqrt{25}$$

Calculate the square root of 25 and get 5.

$$-48-5\times 5$$

Multiply 5 and 5 to get 25.

$$-48-25$$

Subtract 25 from -48 to get -73.

$$-73$$

Factor
