Solve 2*1.6*10^-19*2500*10^31/9

$$\frac { 2 \times 1.6 \times 10 ^ { - 19 } \times 2500 \times 10 ^ { 31 } } { 9 }$$

Evaluate

$$\frac{8000000000000000}{9}\approx 8.888888889 \cdot 10^{14}$$

Solution Steps

To multiply powers of the same base, add their exponents. Add -19 and 31 to get 12.

$$\frac{2\times 1.6\times 10^{12}\times 2500}{9}$$

Multiply 2 and 1.6 to get 3.2.

$$\frac{3.2\times 10^{12}\times 2500}{9}$$

Calculate 10 to the power of 12 and get 1000000000000.

$$\frac{3.2\times 1000000000000\times 2500}{9}$$

Multiply 3.2 and 1000000000000 to get 3200000000000.

$$\frac{3200000000000\times 2500}{9}$$

Multiply 3200000000000 and 2500 to get 8000000000000000.

$$\frac{8000000000000000}{9}$$

Factor

$$\frac{2 ^ {18} \cdot 5 ^ {15}}{3 ^ {2}} = 888888888888888\frac{8}{9} = 888888888888888.9$$
