## What are two ways to write equivalent algebraic expressions?

3(x + 3) and 3x + 9 are equivalent expressions, because the value of both the expressions remains same for any value of x. The expressions 6(x 2 + y + 2) and 6×2 + 6y + 12 are equivalent expressions and can also be written as 6(x2 + y + 2) = 6×2 + 6y + 12.

## How do you find the value of the expression?

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

## What expression is equivalent to 100000?

Meanwhile, the exponent of the “exponential term” of 100,000 is 5 because the decimal point in the “digit term”, 1, must be moved five times to the right to arrive at 100,000. The exponent is positive because 100,000 is greater than or equal to ten. Therefore, the expression that is equivalent to 100,000 is C. .

## What is it called to find the value of an algebraic expression?

It is called evaluating expression. In order to find the value of an algebraic expression you need to substitute a number for each variable and perform the arithmetic operations and the letters can stand for the numbers and it is called evaluating the expression.

## What is the value of 5 cubed expression?
