Solve 70-4(2*5)-4*9(2*5)^2

$$70 - 4 ( 2 \cdot 5 ) - 4 \cdot 9 ( 2 \cdot 5 ) ^ { 2 }$$

Evaluate

$$-3570$$

Solution Steps

Multiply 4 and 2 to get 8.

$$70-8\times 5-4\times 9\times \left(2\times 5\right)^{2}$$

Multiply 8 and 5 to get 40.

$$70-40-4\times 9\times \left(2\times 5\right)^{2}$$

Subtract 40 from 70 to get 30.

$$30-4\times 9\times \left(2\times 5\right)^{2}$$

Multiply 4 and 9 to get 36.

$$30-36\times \left(2\times 5\right)^{2}$$

Multiply 2 and 5 to get 10.

$$30-36\times 10^{2}$$

Calculate 10 to the power of 2 and get 100.

$$30-36\times 100$$

Multiply 36 and 100 to get 3600.

$$30-3600$$

Subtract 3600 from 30 to get -3570.

$$-3570$$

Factor
