Evaluate

$$100$$

Solution Steps

Multiply 70 and 0.002 to get 0.14.

$$\left(0.14+80\times 0.009+90\times 0.022+100\times 0.033+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Multiply 80 and 0.009 to get 0.72.

$$\left(0.14+0.72+90\times 0.022+100\times 0.033+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Add 0.14 and 0.72 to get 0.86.

$$\left(0.86+90\times 0.022+100\times 0.033+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Multiply 90 and 0.022 to get 1.98.

$$\left(0.86+1.98+100\times 0.033+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Add 0.86 and 1.98 to get 2.84.

$$\left(2.84+100\times 0.033+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Multiply 100 and 0.033 to get 3.3.

$$\left(2.84+3.3+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Add 2.84 and 3.3 to get 6.14.

$$\left(6.14+110\times 0.024+120\times 0.008+130\times 0.002\right)\times 10$$

Multiply 110 and 0.024 to get 2.64.

$$\left(6.14+2.64+120\times 0.008+130\times 0.002\right)\times 10$$

Add 6.14 and 2.64 to get 8.78.

$$\left(8.78+120\times 0.008+130\times 0.002\right)\times 10$$

Multiply 120 and 0.008 to get 0.96.

$$\left(8.78+0.96+130\times 0.002\right)\times 10$$

Add 8.78 and 0.96 to get 9.74.

$$\left(9.74+130\times 0.002\right)\times 10$$

Multiply 130 and 0.002 to get 0.26.

$$\left(9.74+0.26\right)\times 10$$

Add 9.74 and 0.26 to get 10.

$$10\times 10$$

Multiply 10 and 10 to get 100.

$$100$$

Factor

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