Solve 3*1.67*10^-27/4pi*1.5*10^-15

$$\frac { 3 \times 1.67 \times 10 ^ { - 27 } } { 4 \pi \times 1.5 \times 10 ^ { - 15 } }$$

Evaluate

$$\frac{167}{200000000000000\pi }\approx 2.65788755 \cdot 10^{-13}$$

Solution Steps

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

$$\frac{1.67\times 3}{1.5\times 4\pi \times 10^{12}}$$

Multiply 1.67 and 3 to get 5.01.

$$\frac{5.01}{1.5\times 4\pi \times 10^{12}}$$

Multiply 1.5 and 4 to get 6.

$$\frac{5.01}{6\pi \times 10^{12}}$$

Calculate 10 to the power of 12 and get 1000000000000.

$$\frac{5.01}{6\pi \times 1000000000000}$$

Multiply 6 and 1000000000000 to get 6000000000000.

$$\frac{5.01}{6000000000000\pi }$$
