(1/5 + 1/2)^2 +3/10 x 5
You asked:
Evaluate the expression: \({\left( \frac{1}{5} + \frac{1}{2} \right)}^{2} + \frac{3}{10} \cdot 5\)
MathBot Answer:
\[{\left( \frac{1}{5} + \frac{1}{2} \right)}^{2} + \frac{3}{10} \cdot 5 = \frac{199}{100} = 1.99\]
\[\begin{aligned}{\left( \frac{1}{5} + \frac{1}{2} \right)}^{2} + \frac{3}{10} \cdot 5& = \left(\frac{1}{5} + \frac{1}{2}\right)^{2} + \frac{3}{10} \cdot 5\\& = \left(\frac{7}{10}\right)^{2} + \frac{3}{10} \cdot 5\\& = \frac{49}{100} + \frac{3}{10} \cdot 5\\& = \frac{49}{100} + \frac{3}{2}\\& = \frac{199}{100}\end{aligned}\]
