Solve 40*[(15+20)*5+15*20)+5*28*360]

$$40 \times [ ( 15 + 20 ) \times 5 + 15 \times 20 ) + 5 \times 28 \times 360 ]$$

Evaluate

$$69400$$

Solution Steps

Add 15 and 20 to get 35.

$$40\left(35\times 5+15\times 20\right)+5\times 28\times 360$$

Multiply 35 and 5 to get 175.

$$40\left(175+15\times 20\right)+5\times 28\times 360$$

Multiply 15 and 20 to get 300.

$$40\left(175+300\right)+5\times 28\times 360$$

Add 175 and 300 to get 475.

$$40\times 475+5\times 28\times 360$$

Multiply 40 and 475 to get 19000.

$$19000+5\times 28\times 360$$

Multiply 5 and 28 to get 140.

$$19000+140\times 360$$

Multiply 140 and 360 to get 50400.

$$19000+50400$$

Add 19000 and 50400 to get 69400.

$$69400$$

Factor

$$2^{3}\times 5^{2}\times 347$$
