Question

Determinati numarul natural x care verifica egalitatea : a) x^2:3^2=(4^2)^2 b) 441:x=49

Answer 1

x²:3² =(4²)² <=> (x/3)² = 16² <=> x/3 = 16 => x = 16·3 => x = 48

441:x = 49 => 441 = 49·x => x = 441/49 => x = 9

Answer 2

a)x^2=4^4:3^2
x^2=256×9
x=rad(256×9)
x=16×3=48

b)441:x=49
x=441:49=9.
