Answer 1

1° resolver numero dentro de parenteses.
a)1/2-(3/8)= 1/2-3/8= 4-3/8= 1/8
b)(2-1/4)-1/8= 1/4-1/8= 2-1/8= 1/8
c)(3+2/6)-(5-3/30)= 5/6-(2/30)= 5/6-1/15= 5-2/30=3/30
d)√1.69= 1.3
e)√5.76= 2.4
f)√4/9= 2/3
g)√49/36= 7/6
h)
$\sqrt[3]{ \frac{1}{8} }$
1/2
i)20-(4/2)-(-2)+(1/9)÷2
20-2+2+1/9÷2
181/9÷2
181/9.1/2
