Question

Problema:
2/3 - √9/4 + (1/2)al cuadrado + √144 - 1 - √36/25
ayudenme pls

Answer 1

$\frac{2}{3}- \sqrt{ \frac{9}{4}} +( \frac{1}{2})^2+ \sqrt{144}- 1 - \sqrt{ \frac{36}{25}}= \\ \\ \frac{2}{3}- \frac{3}{2} + \frac{1}{4}+ 12- 1 - \frac{6}{5}=\quad buscamos \ MCM \\ \\ \frac{2*20}{3*20}- \frac{3*30}{2*30} + \frac{1*15}{4*15}+ 11* \frac{60}{60} - \frac{6*12}{5*12}=\\ \\ \\ \frac{40}{60}- \frac{90}{60} + \frac{15}{60}+ \frac{660}{60} - \frac{72}{60}= \dfrac{40-90+15+660-72}{60}= \boxed{ \dfrac{553}{60}}$

Espero que te sirva, salu2!!!!
