The base of log, if unspecified, is taken to be 10 so you would be finding the value of the logarithm of 5 to the base 10.
This is the value x, such that 10^x = 5.
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
a, whatever the value is, would be the constant.
In this case N is variable for a math sentence. If the equation is n+7=9 n would equal 2.
The values of a and b would be assumed to be 3 and 10 or 2 and 15.
This expression would be 3x-7.
It is called solving the equation. * * * * * I would suggest that the answer is "evaluating it".
You have to substitute a value for the letter variable in the expression. This is what we call evaluating the algebraic expression. An example would be 3x+1=7, when x=2.
It would help if the expression was given!
It would depend on the expression that you have in mind but chose not to share!
Please include the expression in your question so it can be answered.
No
A variable expression is an expression which contains variables(symbol that represents a certain value). For example, 4a-90. 4a-90 would be the expression an a is a variable
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
It means calculate the value of the expression (i.e. simplify) by mutiplying. So, as a completely random example, if you have an expression like: x(x + 1) then, in this particular case, you would multiply what is outside of the brackets by each term inside the brackets to get: x2 + x.

The exponent would be 10.
