Solve 2(85*25)+2(110*25)+(110*85)+2(110*5)+4(75*5)

$$2(85 \times 25)+2(110 \times 25)+(110 \times 85)+2(110 \times 5)+4(75 \times 5)$$

Evaluate

$$21700$$

Solution Steps

Multiply 2 and 85 to get 170. Multiply 2 and 110 to get 220. Multiply 110 and 85 to get 9350. Multiply 2 and 110 to get 220. Multiply 4 and 75 to get 300.

$$170\times 25+220\times 25+9350+220\times 5+300\times 5$$

Multiply 170 and 25 to get 4250.

$$4250+220\times 25+9350+220\times 5+300\times 5$$

Multiply 220 and 25 to get 5500.

$$4250+5500+9350+220\times 5+300\times 5$$

Add 4250 and 5500 to get 9750.

$$9750+9350+220\times 5+300\times 5$$

Add 9750 and 9350 to get 19100.

$$19100+220\times 5+300\times 5$$

Multiply 220 and 5 to get 1100.

$$19100+1100+300\times 5$$

Add 19100 and 1100 to get 20200.

$$20200+300\times 5$$

Multiply 300 and 5 to get 1500.

$$20200+1500$$

Add 20200 and 1500 to get 21700.

$$21700$$

Factor

$$2^{2}\times 5^{2}\times 7\times 31$$
