Question

40 PONTOS - Determine a razão da PG em cada caso:
A) PG (2,8,...)
B) PG (3, 3/2, ...)
C) PG (Xy, Xy3)
D) PG ( 10elevado a 4, 10 elevado a 7, ...)
E) PG ( X, 4x, 16x, ...)

Answer 1

$Q = \frac{ a_{2} }{ a_{1} }$

a) 8/4 = 2

b) 3/2 . 1/3
3/6 = 1/2

c) xy³/xy = xy²

d) 10⁷/10⁴ = 10³

e) 4x/x = 4
