Solve {l}{9^2+9*0,5}{+0,5^2}

$$\left. \begin{array} { l } { 9 ^ { 2 } + 9 \times 0,5 } \\ { + 0,5 ^ { 2 } } \end{array} \right.$$

Evaluate

$$85,5$$

Solution Steps

Calculate 9 to the power of 2 and get 81.

$$81+9\times 0,5+0\times 5^{2}$$

Multiply 9 and 0,5 to get 4,5.

$$81+4,5+0\times 5^{2}$$

Add 81 and 4,5 to get 85,5.

$$85,5+0\times 5^{2}$$

Calculate 5 to the power of 2 and get 25.

$$85,5+0\times 25$$

Multiply 0 and 25 to get 0.

$$85,5+0$$

Add 85,5 and 0 to get 85,5.

$$85,5$$

Factor

$$\frac{19 \cdot 3 ^ {2}}{2} = 85\frac{1}{2} = 85.5$$
