Evaluate

$$80000000000000000000000000$$

Solution Steps

To multiply powers of the same base, add their exponents. Add -3 and -3 to get -6.

$$\frac{0.8}{0.25\times 10^{-6}\times 0.25\times 1.6\times 10^{-19}}$$

To multiply powers of the same base, add their exponents. Add -6 and -19 to get -25.

$$\frac{0.8}{0.25\times 10^{-25}\times 0.25\times 1.6}$$

Calculate 10 to the power of -25 and get \frac{1}{10000000000000000000000000}.

$$\frac{0.8}{0.25\times \frac{1}{10000000000000000000000000}\times 0.25\times 1.6}$$

Multiply 0.25 and \frac{1}{10000000000000000000000000} to get \frac{1}{40000000000000000000000000}.

$$\frac{0.8}{\frac{1}{40000000000000000000000000}\times 0.25\times 1.6}$$

Multiply \frac{1}{40000000000000000000000000} and 0.25 to get \frac{1}{160000000000000000000000000}.

$$\frac{0.8}{\frac{1}{160000000000000000000000000}\times 1.6}$$

Multiply \frac{1}{160000000000000000000000000} and 1.6 to get \frac{1}{100000000000000000000000000}.

$$\frac{0.8}{\frac{1}{100000000000000000000000000}}$$

Divide 0.8 by \frac{1}{100000000000000000000000000} by multiplying 0.8 by the reciprocal of \frac{1}{100000000000000000000000000}.

$$0.8\times 100000000000000000000000000$$

Multiply 0.8 and 100000000000000000000000000 to get 80000000000000000000000000.
