When x = 2, 4x3 = 32
Since there is no expression given, there is no sensible answer.
The expression would be written as 16 The value of the expression is 1. 1 x 1 x 1 x 1 x 1 x 1 = 1
x = 3/sqrt(2) or 1.5*sqrt(2)

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.
It would help if the expression was given!
7
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
sqrt(x+6) is an expression that can't be simplified.It's a number, whose value depends on the value of 'x'.
When x = 2, 3x + 5 = 11.
