Solve 4.2*10^2div40div12=8.75*10^5(m

$$4.2 \times 10 ^ { 2 } \div 40 \div 12 = 8.75 \times 10 ^ { 5 } ( m$$

Solve for m

$$m=0.000001$$

Steps for Solving Linear Equation

Calculate 10 to the power of 2 and get 100.

$$4.2\times 100\div 40\div 12=8.75\times 10^{5}m$$

Calculate 10 to the power of 5 and get 100000.

$$4.2\times 100\div 40\div 12=8.75\times 100000m$$

Swap sides so that all variable terms are on the left hand side.

$$8.75\times 100000m=4.2\times 100\div 40\div 12$$

The equation is in standard form.

$$875000m=\frac{7}{8}$$

Divide both sides by 875000.

$$\frac{875000m}{875000}=\frac{\frac{7}{8}}{875000}$$

Dividing by 875000 undoes the multiplication by 875000.

$$m=\frac{\frac{7}{8}}{875000}$$

Divide \frac{7}{8} by 875000.

$$m=\frac{1}{1000000}$$
