Question

ayuda con estas ecuaciones
x³+6=70
2X²-5=13
²X-2=7
2X+²25=29​

Answer 1

Explicación paso a paso:

x³ + 6 = 70

x³ = 70 – 6

x³ = 64 /׳✔

X = 4

2x² – 5 = 13

2x² = 13 + 5

2x² = 18

x² = 18/2

x² = 9 /×✔

X = 3

x² – 2 = 7

x² = 7 + 2

x² = 9 /×✔

X = 3

2x² + 25 = 29

2x² = 29 – 25

2x² = 4

x² = 4/2

x² = 2 /×✔

X = ✔2
