Question

Sendo x=3, y=2 e z=1
A) x2. B) y2. C) x3 D) y4 e) z9 f) y5 g) x4 h) z15

Answer 1

Olá,

x = 3, y = 2 e z = 1

a)

x² = 3² = 3·3 = 9

b)

y² = 2² = 2·2 = 4

c)

x³ = x · x² = 3·9 = 27

d)

y⁴ = y² · y² = 4·4 = 16

e)

z⁹ = 1⁹ = 1

f)

y⁵ = y · y⁴ = 2 · 16 = 32

g)

x⁴ = x² · x² = 9 · 9 = 81

h)

z¹⁵ = 1¹⁵ = 1

Answer 2

x = 3; y = 2; z = 1; a) x ^ 2 = 3 ^ 2 = 9; b) y ^ 2 = 2 ^ 2 = 4; c) x^ 3 = 3 ^ 3 = 27; d) y^ 4 = 2 ^ 4 = 16; e) z ^ 9 = 1 ^ 9 = 1; f) y ^ 5 = 2 ^ 5 = 32; g) x ^ 4 = 3 ^ 4 = 81; H) z ^ 15 = 1 ^ 15 = 1
