Question

what is the product of (-6.8) squared. simplify the expression. square root of -196

Answer 1

(-6.8)^2
The product of a squared negative number is ALWAYS positive.
So (-6.8)^2 = 46.24

√(-196) Is impossible.
What's under the radical MUST ALWAYS be positive. The square root of a negative number doesn't exist, so is impossible to calculate.

Hope this Helps! :)
