2+2 = 2*2 = 2^2 all simplify to 4. But there is no special name for the three expressions.
Equivalent expressions.
you test it by giving the letters a value say if X equals 5 and Y equals 7 then you calculate both expressions with that value. If both answers are the same, then the simplified expression is correct, or an equivalent.
Because it is proportionally the same value.
If both equations can be simplified to the same value, they are equal.
You can replace a variable with an equal value or expression. Just make sure the same variable always gets the same value or expression.
An equivalent expression.
To determine if two numbers or expressions are equal, you can simplify both sides of the equation and see if they yield the same value. This may involve performing arithmetic operations, factoring, or using algebraic rules. For numerical values, you can directly compare them. If both sides simplify to the same expression or numerical value, they are equal; otherwise, they are not.
Equivalent Expression
Sample Answer: To verify, a number needs to be substituted for x in both expressions. Use order of operations to simplify and find the value. The value needs to be the same for both expressions to prove equivalence.
equivalent expression
To simplify numbers and letters, combine like terms by adding or subtracting coefficients of the same variable. For example, in the expression 3x + 5x, you can simplify it to 8x. For numerical expressions, perform arithmetic operations to reduce the expression to its simplest form, such as turning 4 + 2 to 6. Always ensure to follow the order of operations (PEMDAS/BODMAS) when simplifying complex expressions.

If we are talking about the algebraic expressions, then an expression can be simplified or be evaluated for specific values of its variables, while an equation need to be solved, in other words to find the values of the variables that make the equation a true statement. If we are solving an equation, then we can work in the same way that we can simplify an expression (since an equation is a statement that states that two expressions are equal), or factoring an expression.
To add two rational expressions with the same denominator, you simply add the numerators together while keeping the denominator unchanged. The result is a new rational expression represented as (\frac{a + b}{c}), where (a) and (b) are the numerators of the original expressions, and (c) is the common denominator. Make sure to simplify the resulting expression if possible.
Equivalent expressions.
Yes, numerical expressions can have the same value. For example, the expressions 2+3 and 5 both have the value of 5. Similarly, the expressions 2x3 and 6 both have the value of 6. In general, any two numerical expressions that evaluate to the same number will have the same value.
Learn the properties, and apply them! What properties you use depends on the specific situations; some examples include:* Combine like terms (terms with the same variables), e.g.: 4x + 5x = 9x * Factor expressions * Multiply factors, so you can combine them with other expressions. In a way, this is the opposite of the previous point.
