Solve {l}{0,2*sqrt{100}}{-1/2sqrt{25}}

$$\left. \begin{array} { l } { 0,2 \cdot \sqrt { 100 } } \\ { - \frac { 1 } { 2 } \sqrt { 25 } } \end{array} \right.$$

Evaluate

$$-0,5$$

Solution Steps

Calculate the square root of 100 and get 10.

$$0,2\times 10-\frac{1}{2}\sqrt{25}$$

Multiply 0,2 and 10 to get 2.

$$2-\frac{1}{2}\sqrt{25}$$

Calculate the square root of 25 and get 5.

$$2-\frac{1}{2}\times 5$$

Express -\frac{1}{2}\times 5 as a single fraction.

$$2+\frac{-5}{2}$$

Fraction \frac{-5}{2} can be rewritten as -\frac{5}{2} by extracting the negative sign.

$$2-\frac{5}{2}$$

Convert 2 to fraction \frac{4}{2}.

$$\frac{4}{2}-\frac{5}{2}$$

Since \frac{4}{2} and \frac{5}{2} have the same denominator, subtract them by subtracting their numerators.

$$\frac{4-5}{2}$$

Subtract 5 from 4 to get -1.

$$-\frac{1}{2}$$

Factor

$$-0,5$$
