Solve 0.75*10^-4*8.3*10^3*400

$$0.75 \times 10 ^ { - 4 } \times 8.3 \times 10 ^ { 3 } \times 400$$

Evaluate

$$249$$

Solution Steps

To multiply powers of the same base, add their exponents. Add -4 and 3 to get -1.

$$0.75\times 10^{-1}\times 8.3\times 400$$

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

$$0.75\times \frac{1}{10}\times 8.3\times 400$$

Multiply 0.75 and \frac{1}{10} to get \frac{3}{40}.

$$\frac{3}{40}\times 8.3\times 400$$

Multiply \frac{3}{40} and 8.3 to get \frac{249}{400}.

$$\frac{249}{400}\times 400$$

Multiply \frac{249}{400} and 400 to get 249.

$$249$$

Factor

$$3\times 83$$
