Question

Sendo x= (0,5)², y= $\sqrt[3]{0,343}$ e z= $\sqrt{0,04}$, calcule os dados a seguir
a) x + y + z
b) y · z
c) x ÷ z
d) x - y - z
( POR FAVOR TODAS EM CÁLCULO )

Answer 1

Oi Geovanna

x = 0.5² = (1/2)² = 1/4
y = ³√0.343 = 7/10 
z = √0.04 = 0.2 = 1/5 

a)

x + y + z = 1/4 + 7/10 + 1/5
x + y + z = 5/20 + 14/20 + 4/20 = 23/20 

b)

y*z = (7/10)*(1/5) = 7/50 

c)

x/z = (1/4)/(1/5) = (1/4)*(5/1) = 5/4 

d) 

x - y - z = 1/4 + 7/10 + 1/5
x - y - z = 5/20 - 14/20 - 4/20 = -13/20
