Question

efectuati ecuatiile :x la puterea 2 : 3 la puterea 2=(4 la puterea 2) totul la a 2

Answer 1

x² :3² = (4²)²
(x:3)² = 16² ⇒ x:3=16
x=16 *3
x=48

Answer 2

$\it x^2:3^2=(4^2)^2 \Longrightarrow \sqrt{ x^2:3^2} =\sqrt{(4^2)^2} \Longrightarrow x:3=4^2\Longrightarrow$

$\it \Longrightarrow \dfrac{x}{3} =16 \Longrightarrow x = 3\cdot16 \Longrightarrow x = 48\ .$
