Evaluate 3(a + b + c)2 for a = 2, b = 3, and c = 4

243

Step-by-step explanation:

We have the expression

Note that the expression depends on 3 variables

a, b and c

in this case we want to evaluate the expression for

Then change the variable a by the number 2, the variable b by the number 3 and the variable c by the number 4

So we have

Now simplify the expression

The answer is 243

ANSWER

EXPLANATION

The given expression is

We want to evaluate this expression for:

a = 2, b = 3, and c = 4.

We substitute the given values into the expression to get:

Let us perform the addition inside the parenthesis to get:

Therefore the given expression evaluates to:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
