Question

Potrzebuję rozwiązania:
(1,7)*x*10^(-5)=x^3

Answer 1

(1,7)*10⁻⁵*x = x³

17*10⁻¹*10⁻⁵*x = x³

17*10⁻⁶*x = x³

x³ - 17*10⁻⁶*x = 0

x[x² - 17*(10⁻³)²] = =

x = 0 lub x² - 17*(10⁻³)² = 0

x = 0 lub x - √17/1000 = 0 lub x + √17/1000 = 0

x = 0 lub x = √17/1000 lub x = - √17/1000

Answer 2

(1,7)×x×10⁻⁵=x³
1,7x×1/10⁵=x³/:x
1⁷/₁₀×¹/₁₀₀₀₀₀=x²
¹⁷/₁₀×¹/₁₀₀₀₀₀=x²
x=√¹⁷/₁₀₀₀₀₀₀
x= +(-)0,001√17

Answer 3
