Question

Use the square root symbol to solve ×squard= -64

Answer 1

The equation ×squard = -64 involves finding a number that, when multiplied by itself, equals -64. However, it is not possible to find a real number that satisfies this equation since the square of any real number is always positive (or zero) in algebraic systems that follow the conventional rules. In other words, there are no real solutions to this equation.

However, in complex numbers, there is a solution. The square root of -64 is 8i, where i represents the imaginary unit (√-1).
