Katrina says that the expression 5,432 + 4,564 + 13,908 +61n can be evaluated by adding 5,432 + 4,564 +13,908 and then dividing by the value of 61n. Do you agree? Explain.​

Final answer:

No, the expression cannot be evaluated by adding first and dividing by 61n. The correct order of operations should be followed.

Step-by-step explanation:

No, I do not agree with Katrina's approach. The expression 5,432 + 4,564 + 13,908 + 61n cannot be evaluated by adding 5,432 + 4,564 + 13,908 first and then dividing by the value of 61n. The reason is that the addition and division operations have different precedence in mathematics. To correctly evaluate the expression, we need to simplify it using the order of operations.

First, we add the numbers 5,432, 4,564, and 13,908 to get a sum of 23,904. Then, we multiply 61 and n together. Finally, we add the sum of 23,904 to the product of 61 and n. The simplified expression would be 23,904 + 61n.

So, the expression cannot be simplified or evaluated as suggested by Katrina. Instead, we use the correct order of operations to simplify and evaluate it.

Answer: Nope.

Step-by-step explanation: The expression 5,432 + 4,564 + 13,908 + 61n cannot be evaluated by adding 5,432 + 4,564 + 13,908 and then dividing by the value of 61n. This is because the +61n term is not part of the addition being performed on the first three terms. The +61n term is separate and would need to be evaluated separately in order to find the value of the entire expression.

Instead, the correct way to evaluate the expression 5,432 + 4,564 + 13,908 + 61n would be to first add the first three terms together to get 23,904, and then evaluate the +61n term separately by substituting the value of n into the expression and performing the necessary calculations. For example, if n=2, the expression would be evaluated as follows:

5,432 + 4,564 + 13,908 + 61(2)

= 23,904 + 122

= 24,026

Therefore, the correct way to evaluate the expression 5,432 + 4,564 + 13,908 + 61n is to add the first three terms together and then evaluate the +61n term separately.
