Solve 3.14*80*5+3.14*(80div2)^2*2=0

$$3.14 \times 80 \times 5 + 3.14 \times ( 80 \div 2 ) ^ { 2 } \times 2 = 0$$

Verify

Solution Steps

Multiply 3.14 and 80 to get 251.2.

$$251.2\times 5+3.14\times \left(\frac{80}{2}\right)^{2}\times 2=0$$

Multiply 251.2 and 5 to get 1256.

$$1256+3.14\times \left(\frac{80}{2}\right)^{2}\times 2=0$$

Divide 80 by 2 to get 40.

$$1256+3.14\times 40^{2}\times 2=0$$

Calculate 40 to the power of 2 and get 1600.

$$1256+3.14\times 1600\times 2=0$$

Multiply 3.14 and 1600 to get 5024.

$$1256+5024\times 2=0$$

Multiply 5024 and 2 to get 10048.

$$1256+10048=0$$

Add 1256 and 10048 to get 11304.

$$11304=0$$

Compare 11304 and 0.

$$\text{false}$$
