Solve f(1,1)=1,9^3-8/1,1-2

$$f ( 1,1 ) = \frac { 1,9 ^ { 3 } - 8 } { 1,1 - 2 }$$

Solve for f

$$f=-\frac{72100}{99}\approx -728,282828283$$

Steps for Solving Linear Equation

Calculate 9 to the power of 3 and get 729.

$$f\times 1,1=\frac{1\times 729-8}{1,1-2}$$

Multiply 1 and 729 to get 729.

$$f\times 1,1=\frac{729-8}{1,1-2}$$

Subtract 8 from 729 to get 721.

$$f\times 1,1=\frac{721}{1,1-2}$$

Subtract 2 from 1,1 to get -0,9.

$$f\times 1,1=\frac{721}{-0,9}$$

Expand \frac{721}{-0,9} by multiplying both numerator and the denominator by 10.

$$f\times 1,1=\frac{7210}{-9}$$

Fraction \frac{7210}{-9} can be rewritten as -\frac{7210}{9} by extracting the negative sign.

$$f\times 1,1=-\frac{7210}{9}$$

Divide both sides by 1,1.

$$f=\frac{-\frac{7210}{9}}{1,1}$$

Express \frac{-\frac{7210}{9}}{1,1} as a single fraction.

$$f=\frac{-7210}{9\times 1,1}$$

Multiply 9 and 1,1 to get 9,9.

$$f=\frac{-7210}{9,9}$$

Expand \frac{-7210}{9,9} by multiplying both numerator and the denominator by 10.

$$f=\frac{-72100}{99}$$

Fraction \frac{-72100}{99} can be rewritten as -\frac{72100}{99} by extracting the negative sign.

$$f=-\frac{72100}{99}$$
