Solve for j.

Question

196 = j2

Answer 1

To solve for j, we need to isolate j on one side of the equation.

To do that, we divide both sides of the equation by 2:

196/2 = j^2/2

98 = j^2/2

Now, we can multiply both sides of the equation by 2 to eliminate the fraction:

98 * 2 = j^2

196 = j^2

Taking the square root of both sides gives us:

j = ±√196

j = ±14

Therefore, the solutions for j are j = 14 or j = -14.
