Solve |4(2)-(1)/3^2

$$\frac { | 4 ( 2 ) - ( 1 ) } { 3 ^ { 2 } }$$

Evaluate

$$\frac{7}{9}\approx 0.777777778$$

Solution Steps

Multiply 4 and 2 to get 8.

$$\frac{|8-1|}{3^{2}}$$

Subtract 1 from 8 to get 7.

$$\frac{|7|}{3^{2}}$$

The absolute value of a real number a is a when a\geq 0, or -a when a<0. The absolute value of 7 is 7.

$$\frac{7}{3^{2}}$$

Calculate 3 to the power of 2 and get 9.

$$\frac{7}{9}$$

Factor

$$\frac{7}{3 ^ {2}} = 0.7777777777777778$$
