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

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)

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

Prove that the value of the expression (125^2+25^2)(5^2–1) is divisible by 3

Radda [10]

Step-by-step explanation:

$A =(125^{2} + 25^{2} ) (5^{2} - 1)\\A = [(5^{3})^{2} + (5^{2})^{2} ] . (5^{2} - 1)\\A = (5^{6} + 5^{4} ). (5^{2} - 1)\\A = [5^{4} . ( 5^{2} + 5)].(5^{2} - 1) \\A = 5^{4} . (25+ 5). (5^{2} - 1)\\A = 5^{4} . 30. (5^{2} - 1)\\$

Since 30 is divisible by 3

Thus, A is divisible by 3

Good luck!
