U^2= 81

Question

Solve where u is a real number
Find if there are multiple answers or no solutions

Answer 1

To solve the equation U^2 = 81, we need to find the value of U that satisfies this equation.

Taking the square root of both sides, we have:

U = ±√81

Simplifying the square root of 81, we have:

U = ±9

Therefore, the solutions to the equation U^2 = 81 are U = 9 or U = -9.

There are two possible answers, U = 9 and U = -9.
