Consider the expressions** 3 2 + 1 and 5 × 2**. Both are equal to 10. That is, they are equivalent expressions. Now let us consider some expressions that include variables, say 5 x + 2. The expression can be rewritten as 5 x + 2 = x + x + x + x + x + 1 + 1.

**expressions that work the same even though they look different**. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

##
How do you identify equivalent expressions?

**Equivalent** **Expressions** **Equivalent** **Expressions** are **expressions** that have the same value. They may look different but will have the same result if calculated. For example, and are **equivalent** **expressions**. See why below: The two **expressions** have the same answer, 27. Therefore, we can say that they are **equivalent** **expressions**.

##
How do you find the equivalent expression?

equivalent expressionshave the same value but are presented in a differentformat using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not “equal”, hence we should use 3 parallel lines in the”equal” rather than 2 as shown here.

##
How to solve equivalent expressions?

**Equivalent** equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or **expression** to both sides of an equation produces an **equivalent** equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an **equivalent** equation.

How to write equivalent expression?

equivalentleft (x+x,3xright) equivalent(x+x,3x) 2. Apply the formula: e q u i v a l e n t ( a, b) mathrm {equivalent}left (a,bright) equivalent(a,b) =false, where. a = x + x. a=x+x a= x+x and. b = 3 x. b=3x b =3x.

What is an example of an equivalent expression?

Examples of Equivalent Expressions 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6×2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.

Which expression is equivalent to st6?

1 Answer. s(6) × t(6) is equivalent to (st)(6).

What does it mean for expressions to be equivalent?

What are equivalent expressions? Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

Which expression is equivalent to the square root of 80?

√80 = 4√5. Therefore, the square root of 80 in radical form is 4√5.

Which expression is equivalent to square root of 252?

Summary: If f(x) = 3 – 2x and g(x) = 1/x + 5, then the value of (f/g)(8) value is -169.

How does Sal find equivalent expressions?

Sal finds equivalent expressions** by combining like terms and using the distributive property. **

Why do brackets and parentheses have to include the other one?

Brackets [] and Parentheses () both have to include the other one because** you could see both. ** It also reminds us that division and multiplication are on the same level, so generally done left to right. Also, addition and subtraction are on the same level left to right.
