Question

x.x.x=27
x.y.y=75
x.y.w.w=23
x.y.w=?

Answer 1

x.x.x=27x.y.y=75
x.y.w.w=23
x.y.w=?

====
x . x. x = 27
x³ = 27
x = ∛27
x = 3

===
Substituir o valor de x = 3

x.y.y=75

3.y²=75
y² = 75/3
y² = 25
y = √25
y = 5

===
Substituir o valor de x = 3 e y = 5

x.y.w.w=23

x.y.w.w=23
3.5.w² = 23
15w² = 23
w² = 23/15
w = √(23/15)
w = √23 . √15 / √15.√15
w = √345 / √15²
w = √345 / 15

===
x.y.w=?

Substitui os valore de x = 3, y - 5 e w = √345/15

x.y.w
3.5. √345/15  
15.√345/15  (corta 15 com 15)

x.y.w = √345
