In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer
When you replace the variable with a number and perform the operations, you evaluate an expression. This process involves substituting the numerical value for the variable and simplifying the expression according to the given operations. Evaluation is a fundamental concept in mathematics and is used to determine the value of the expression under specific conditions.
To evaluate an expression means to find its numerical value. A power consists of a base and an exponent. According to the order of operations, operations inside parentheses (or other grouping symbols) are performed first, followed by the evaluation of powers ... then (*/) and (+-).
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
36.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.5
