ALGEBRA Solve each equation. Round to the nearest tenth, if necessary.
a² = 64
a = ±8.0
To solve the equation a² = 64, we need to find the value of a.
To do this, we'll take the square root of both sides of the equation:
√(a²) = √64
This simplifies to:
a = ±√64
Taking the square root of 64 gives us two possible solutions: a = ±8.
Therefore, the solutions to the equation a² = 64 are a = 8 and a = -8.
