6.

a)1+3+5=9=3^2 pătrat perfect

b)1+3+5+7=16=4^2 pătrat perfect

7.

a)8=2^3 =>x=3

b)x^3 = 1^3 =>x=1

c)125=5^3 =>x=5

d)1000=10^3 =>x=10

Answer 2

1 + 3 + 5 = 4 + 5 = 9 = 3 x 3 = 3²

1 + 3 + 5 + 7 = 4 + 12 = 16 = 4 x 4 = 4²

x³ = 8

x³ = 2³

x = 2

x³ = 1

x³ = 1³

x = 1

x³ = 125

x³ = 5³

x = 5

x³ = 1000

x³ = 10³

x = 10
