Solve L_{f}=16.5[1+11.5*10^-6(58-22)]

$$L _ { f } = 16.5 [ 1 + 11.5 \times 10 ^ { - 6 } ( 58 - 22 ) ]$$

Solve for L_f

$$L_{f}=16.506831$$

Steps for Solving Linear Equation

Calculate 10 to the power of -6 and get \frac{1}{1000000}.

$$L_{f}=16.5\left(1+11.5\times \frac{1}{1000000}\left(58-22\right)\right)$$

Multiply 11.5 and \frac{1}{1000000} to get \frac{23}{2000000}.

$$L_{f}=16.5\left(1+\frac{23}{2000000}\left(58-22\right)\right)$$

Subtract 22 from 58 to get 36.

$$L_{f}=16.5\left(1+\frac{23}{2000000}\times 36\right)$$

Multiply \frac{23}{2000000} and 36 to get \frac{207}{500000}.

$$L_{f}=16.5\left(1+\frac{207}{500000}\right)$$

Add 1 and \frac{207}{500000} to get \frac{500207}{500000}.

$$L_{f}=16.5\times \frac{500207}{500000}$$

Multiply 16.5 and \frac{500207}{500000} to get \frac{16506831}{1000000}.

$$L_{f}=\frac{16506831}{1000000}$$

Assign L_f

$$L_{f}≔16.506831$$
