Question

Calcula las raíces cuadradas.
a. 1/4
b. 36/25
c. 100/31
d. 121/49

Answer 1

Respuesta:

a=$\sqrt{\frac{1}{4} } =\frac{1}{2}$

b=$\sqrt{\frac{36}{25} } =\frac{\sqrt{36} }{\sqrt{25} }=\frac{6}{5}$

c=$\sqrt{\frac{100}{31} } =\frac{\sqrt{100} }{\sqrt{31} } = \frac{10}{\sqrt{31} }\frac{\sqrt{31} }{31}=\frac{10\sqrt{31} }{31}$

d=$\sqrt{\frac{121}{49} } =\frac{\sqrt{121} }{49} =\frac{11}{7}$
