What is it called to find the value of a mathematical expression?
It is called "to evaluate" the expression.
Whats is the value of the expression if x equals 2?
It would help if the expression was given!
What is the value of the expression when y equals 8?
Depends what the expression is. Just plug in 8 for y in the expression and that'll do it for you.
Using exactly two 2s and any of the standard mathematical symbols write down an expression whose value is 5?
square root of 0.2^-2=5
What is mathematical or numerical expression?
It is a combination of numbers and variables, linked together by mathematical functions. For example sqrt(2y/3*7.34*pi) where y is some variable. Given the value(s) of the variable(s) it is possible to evaluate (find the value of) the expression.

What is a mathematical expression?
Any "expression" that represents a numeric value. Example: 2+2=4 or x+7=10. Actually the examples above are equations, not expressions. Expressions do not have = signs. 7a and 4x are examples.
The numerical value of an expression?
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.
What is expressions in maths?
A mathematical expression is a mathematical phrase that consist numbers variables and signs of operation example: x(variable) + 5(number)=7 so the value of x is 2 -Kennethn 10 yrs. old :]

Is it true When the base of an exponential expression is 1 the value of the expression always equals 1?
Yes.
What is the expression for x equals 3 and y equals 6?
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.

What its the expression that have the same value on both sides of the equals sign?
The = sign
What its the expression that have the same value on bothes sides of the equals sign?
The = sign
