To solve the equation \( 196 = j^2 \), we need to isolate \( j \).
-
Take the square root of both sides: \[ j = \pm\sqrt{196} \]
-
Calculate the square root: \[ \sqrt{196} = 14 \]
-
Therefore, the solutions are: \[ j = 14 \quad \text{or} \quad j = -14 \]
So, the possible responses for \( j \) are \( 14 \) and \( -14 \).
