Question

Is there an error in this statement If x2 = 25, then x = 5.

Answer 1

Yes there is an error in this statement.

because x^2 = 25 
so x = 5...this is one condition

Another condition is x = -5
(-5)^2 = 25 (this is also true)

Answer 2

No because 5 to the power of 2 equals 5 x 5 and 5 x 5 = 25 hope this helped
