(3*5)+(6 to the power of 2)+54-5
It is called "to evaluate" the 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.
Is the value obtained when all the variables have been given their value and the expression has been calculated according to mathematical rules.
It would help if the expression was given!
Depends what the expression is. Just plug in 8 for y in the expression and that'll do it for you.

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 :]

square root of 0.2^-2=5
Yes.
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.
The value of a keyword as a real number is its numerical representation in the context of a mathematical expression or equation.
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.
