To solve an algebraic expression, simplify the expression by combining like terms, isolate the variable on one side of the equation by using inverse operations. then, solve the equation by finding the value of the variable that makes the equation true.
Solved Evaluate The Expression A2 2ab ï When A 7 ï And B 5 Chegg 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. example \(\pageindex{1}\): evaluate evaluate \(x 7\) when. Free math problem solver answers your algebra homework questions with step by step explanations. Following “tips for evaluating algebraic expressions,” first re place all occurrences of variables in the expression x2 − 2xy y2 with open parentheses. secondly, replace each variable with its given value, and thirdly, follow the “rules guiding order of operations” to evaluate the resulting expression. if x = −2 and y = −1, evaluate x3 − y3. Strategy we will replace each x and y in the expression with the given value of the variable, and evaluate the expression using the order of operation rules.why to evaluate an expression means to find its numerical value, once we know the value of its variable(s).solutiona.

Answer: the final result is 268435456. step by step explanation: given that a = 2 and b = 7, we can simply plug in our numbers into the variable and begin to evaluate. a²ᵃᵇ becomes 2²°²°⁷, which means we simply multiply the values in the exponential position. this comes out to be 2²⁸, which brings us our final result when evaluated. answer:. To find the value of 2 ab when a = 7 and b = 2, we can follow these steps: write down the expression: the expression we need to evaluate is 2 ab. substitute the values of a and b: 2 ab = 2 × 7 × 2. perform the multiplication: first, we can multiply 2 and 7: 2 × 7 = 14 next, multiply the result by 2: 14 × 2 = 28. therefore, 2 ab = 28. Factorise the following, using the identity a 2 2ab b 2 = (a b) 2. x 2 12x 36. find the length of the side of the given square if area of the square is 625 square units and then find the value of x.
