Solved Evaluate The Expression A2 2ab ï When A 7 ï And B 5 Chegg The video explains how to perform substitution and evaluate an expression using the order of operations. mathispower4u more. To determine if the expressions a b 2 and a 2 b 2 are equivalent, we can analyze each expression step by step: evaluate the first expression a b 2: this expression means to multiply a by b squared, which can be expressed as: a b 2 = a × (b × b) this simplifies to a × b 2. evaluate the second expression a 2 b 2:.
Solved Evaluate The Following Algebraic Expression At A 5 Chegg In this section we will evaluate algebraic expressions for given values of the variables contained in the expressions. here are some simple tips to help you be successful. replace all occurrences of variables in the expression with open parentheses. leave room between the parentheses to substitute the given value of the variable. But both answers should be correct as (a − b)2 = (b − a)2 =a2 b2 − 2ab (a − b) 2 = (b − a) 2 = a 2 b 2 − 2 a b. so my question is: what would the answer be: a − b a − b or b − a b − a ? you should note x2−−√ =|x| x 2 = | x | not x x. the answer is undisputably. |a − b| | a − b |. or if you prefer. The answer is undisputably |a b| or if you prefer \begin{cases}a\ge b\to a b\\a\le b\to b a.\end{cases} you can also evaluate it as \max(a,b) \min(a,b) or \max(a b,b a). whats the difference between (a^2 b^2 2ab) and ((a b)^2)?. In this section, we’ll evaluate expressions—again following the order of operations. 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. solution: 1. to evaluate, substitute 3 3 for x x in the expression, and then simplify. substitute. add.
Evaluate An Expression In The Form A 2 B 2 A B Example 1 The answer is undisputably |a b| or if you prefer \begin{cases}a\ge b\to a b\\a\le b\to b a.\end{cases} you can also evaluate it as \max(a,b) \min(a,b) or \max(a b,b a). whats the difference between (a^2 b^2 2ab) and ((a b)^2)?. In this section, we’ll evaluate expressions—again following the order of operations. 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. solution: 1. to evaluate, substitute 3 3 for x x in the expression, and then simplify. substitute. add. Expand (a b)(a2 −ab b2) (a b) (a 2 a b b 2) by multiplying each term in the first expression by each term in the second expression. a⋅a2 a(−ab) ab2 ba2 b(−ab) b⋅b2 a ⋅ a 2 a ( a b) a b 2 b a 2 b ( a b) b ⋅ b 2. simplify terms. tap for more steps. To evaluate an algebraic expression for a given value, you have to substitute the variable of the expression for the value and perform all the arithmetic operations of the expression. for example, to evaluate the expression 3x 5 for x=1, you have to replace the variable x with the number 1 and perform the calculations: 3(1) 5=8. Equations : tiger algebra gives you not only the answers, but also the complete step by step method for solving your equations (a b)(a2 b2) (a2 b2) so that you understand better. 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.
