Solve {r}{8*8*10^-8m}{-56*10^-7*3}

$$\left. \begin{array} { r } { 8 \times 8 \times 10 ^ { - 8 } m } \\ { - 56 \times 10 ^ { - 7 } \times 3 } \end{array} \right.$$

Evaluate

$$\frac{m}{1562500}-\frac{21}{1250000}$$

Solution Steps

Multiply 8 and 8 to get 64.

$$64\times 10^{-8}m-56\times 10^{-7}\times 3$$

Calculate 10 to the power of -8 and get \frac{1}{100000000}.

$$64\times \frac{1}{100000000}m-56\times 10^{-7}\times 3$$

Multiply 64 and \frac{1}{100000000} to get \frac{1}{1562500}.

$$\frac{1}{1562500}m-56\times 10^{-7}\times 3$$

Calculate 10 to the power of -7 and get \frac{1}{10000000}.

$$\frac{1}{1562500}m-56\times \frac{1}{10000000}\times 3$$

Multiply 56 and \frac{1}{10000000} to get \frac{7}{1250000}.

$$\frac{1}{1562500}m-\frac{7}{1250000}\times 3$$

Multiply \frac{7}{1250000} and 3 to get \frac{21}{1250000}.

$$\frac{1}{1562500}m-\frac{21}{1250000}$$

Factor

$$\frac{4m-105}{6250000}$$

Solution Steps

Factor out \frac{1}{6250000}.

$$\frac{4m-105}{6250000}$$
