Solve (5.99*10^+9pi)(1.6*10^-19)(1.6*10^-19)

$$( 5.99 \times 10 ^ { + 9 } \pi ) ( 1.6 \times 10 ^ { - 19 } ) ( 1.6 \times 10 ^ { - 19 } )$$

Evaluate

$$\frac{599\pi }{3906250000000000000000000000000}\approx 4.817443839 \cdot 10^{-28}$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 9 and -19 to get -10.

$$5.99\times 10^{-10}\pi \times 1.6\times 1.6\times 10^{-19}$$

To multiply powers of the same base, add their exponents. Add -10 and -19 to get -29.

$$5.99\times 10^{-29}\pi \times 1.6\times 1.6$$

Calculate 10 to the power of -29 and get \frac{1}{100000000000000000000000000000}.

$$5.99\times \frac{1}{100000000000000000000000000000}\pi \times 1.6\times 1.6$$

Multiply 5.99 and \frac{1}{100000000000000000000000000000} to get \frac{599}{10000000000000000000000000000000}.

$$\frac{599}{10000000000000000000000000000000}\pi \times 1.6\times 1.6$$

Multiply \frac{599}{10000000000000000000000000000000} and 1.6 to get \frac{599}{6250000000000000000000000000000}.

$$\frac{599}{6250000000000000000000000000000}\pi \times 1.6$$

Multiply \frac{599}{6250000000000000000000000000000} and 1.6 to get \frac{599}{3906250000000000000000000000000}.

$$\frac{599}{3906250000000000000000000000000}\pi$$
