Question

stabiliti daca sunt patrate perfecte. a=3^3×2×3^5×2^9×5^4 b=5^3n+1×5^n+5:5^2n-4
va rog urgent ma abonez si dau coroana la care raspunde

Answer 1

Răspuns:

Explicație pas cu pas:

a=3^3×2×3^5×2^9×5^4 = 3³ * 2 * 3⁵ * 2⁹ * 5⁴ = 3⁸ * 2¹⁰ * 5⁴ = (3⁴ * 2⁵ * 5²)² - patrat perfect

b=5^3n+1×5^n+5:5^2n-4 = 5³ⁿ⁺¹ * 1 * 5ⁿ⁺⁵ : 5²ⁿ⁻⁴ = 5⁴ⁿ⁺⁶ : 5²ⁿ⁻⁴ = 5²ⁿ⁺² = (5ⁿ⁺¹)² - patrat prfect
