Question

aflati numarul natural x, stiind ca x^3=(15^2+35):52+(3·2^2)^2-(5+1^3)·4

^=ridicare la putere
Punctul mic ->·=înmulțire

Answer 1

Explicație pas cu pas:

x³ = ( 15² + 35 ) : 52 + ( 3 · 2² )² - ( 5 + 1³ ) · 4

x³ = ( 225 + 35 ) : 52 + ( 3 · 4 )² - ( 5 + 1 ) · 4

x³ = 260 : 52 + 12² - 6 · 4

x³ = 5 + 144 - 24

x³ = 149 - 24

x³ = 125

x³ = 5³

x = 5

Answer 2

x³=(15²+35):52+(3×2²)²-(5+1³)×4=

x³=(225+35):52+(3×4)²-(5+1)×4=

x³=260÷52+12²-6×4=

x³=5+144-24=

x³=125

x³=5³

x=5
