Question

4*√1/4 +5*√1/25+(1/3)-¹ -(1/2)-²

Answer 1

Resposta:

$4.\sqrt{\frac{1}{4} } +5.\sqrt{\frac{1}{25} } +(\frac{1}{3} )^{-1} -(\frac{1}{2} )^{-2} =\\ \\ \\ 4.\frac{\sqrt{1} }{\sqrt{4} } +5.\frac{\sqrt{1} }{\sqrt{25} } +\frac{1}{(\frac{1}{3})^{1} } -\frac{1}{(\frac{1}{2} )^{2} } =\\ \\ \\ 4.\frac{1}{2} +5.\frac{1}{5} +(1.\frac{3}{1} )-1.\frac{4}{1} =\\ \\ \\ \frac{4}{2} +\frac{5}{5} +3-4=\\ \\ 2+1+3-4=2\\ \\ \\ resultado=2$
