Solve 75,000=x*(1+0.1)^21

$$75,000 = x \cdot ( 1 + 0.1 ) ^ { 21 }$$

Solve for x

$$x = \frac{75000000000000000000000000}{7400249944258160101211} = 10134\frac{5.867064887799519 \times 10^{21}}{7.40024994425816 \times 10^{21}} \approx 10134.792819828$$

Steps for Solving Linear Equation

Add 1 and 0.1 to get 1.1.

$$75000=x\times 1.1^{21}$$

Calculate 1.1 to the power of 21 and get 7.400249944258160101211.

$$75000=x\times 7.400249944258160101211$$

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

$$x\times 7.400249944258160101211=75000$$

Divide both sides by 7.400249944258160101211.

$$x=\frac{75000}{7.400249944258160101211}$$

Expand \frac{75000}{7.400249944258160101211} by multiplying both numerator and the denominator by 1000000000000000000000.

$$x=\frac{75000000000000000000000000}{7400249944258160101211}$$
