Solve =(1.72*10^-3)*(3)/(0.73*10^-13)

$$= \frac { ( 1.72 \times 10 ^ { - 3 } ) \times ( 3 ) } { ( 0.73 \times 10 ^ { - 13 } ) }$$

Evaluate

$$\frac{5160000000000}{73}\approx 70684931506.849315068$$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{1.72\times 3\times 10^{10}}{0.73}$$

Multiply 1.72 and 3 to get 5.16.

$$\frac{5.16\times 10^{10}}{0.73}$$

Calculate 10 to the power of 10 and get 10000000000.

$$\frac{5.16\times 10000000000}{0.73}$$

Multiply 5.16 and 10000000000 to get 51600000000.

$$\frac{51600000000}{0.73}$$

Expand \frac{51600000000}{0.73} by multiplying both numerator and the denominator by 100.

$$\frac{5160000000000}{73}$$

Factor

$$\frac{3 \cdot 43 \cdot 2 ^ {12} \cdot 5 ^ {10}}{73} = 70684931506\frac{62}{73} = 70684931506.84932$$
