25 2x2x2x2x2 = 32
(2x)2 = 4 x2 Its numerical value depends on the value of 'x'.
-25
25, because 5x5=25
The count or number of something. E.g.;If x = 2 then the numerical value of 3x is 6.The numerical value of the constant pi is 3.142...

A numerical expression is ' 2 + 3' A numerical equation is ' 2 + 3 = 5'.
x = 25^2 = 25*25 = 625.
If X is a variable, X to the 25 = x^25 = x^5^2 = x^2^5. Because X is only a variable (with no assigned value), a power of X will not produce a numeric value.
It is: 5^2 = 25
251.5 = 253/2 = [ sqrt(25) ]3 = 53 = 125
4x^2 + 9 is a prime algebraic expression. Its numerical value may be prime of not - depending on the value of x.For x = 1, the value of the expression is 13 - a prime whereasfor x = 2, the value of the expression is 25 - not a prime.
