Is the following correct?

\(\displaystyle 3^4 + \frac{3 - \sqrt{121}}{4 × 2}\)

3^4 + (3 - sqrt(121)) / (4*2)

Hi Ladydi. What kind of help do you need? Have you seen any lessons or examples about Order of Operations?I need help with order of operation

We evaluate inside grouping symbols first. A radical sign is a grouping symbol. A fraction bar is a grouping symbol.

Therefore, start in the numerator.

What is √121

What is 3 - √121

Hello again. I'd missed your post above because it was waiting in queue when I'd replied.I'm trying to help my grandson understand this math problem

Have you shown your grandson my questions?

Also, does your grandson have a textbook?

If he needs more instruction, we can help find online lessons for Order of Operations. Otherwise, we can continue going through the evaluation steps with the exercise above.

PS: Your grandson is welcome to communicate with us directly, too.

Ye so here. You need to think order of operations BIDMAS.3to 4th power plus(3-the square root of 121)divided 4x2

The issue with this problem is that the within both the numerator and denominator we do not know what we are diving by or diving into. Therefore the first step is to be clear on what the numerator and denominator are.

Thus put brackets around these. This is the most important step to start.

3^4 + (3-sqrt(121))/(4x2)

Now we do whatever is in the brackets first.

3^4+(3-11)/(8)

3^4+(-8)/(8)

3^4+ -8/8

Now using bidmas we do the indicies first.

81 + -1

81-1 = 80

I liked very much what you said above! You can't divide until you know what you are dividing. That is how I say.The issue with this problem is that the within both the numerator and denominator we do not know what we are diving by or diving into.

On another note, we like to give hints to students so they can figure the solution on their own. That is, we try not to show complete solution.

I see. This person was a parent / grandparent that is why I gave the answer with steps. I will take this into account next time though.I liked very much what you said above! You can't divide until you know what you are dividing. That is how I say.

You responded to a thread that had been inactive for two and a half months. You should have left the thread alone.

I am sure it is not an issue.You responded to a thread that had been inactive for two and a half months. You should have left the thread alone.

I am sure it is not an issue.

I am sure you will try not do it again, because you are to address recent threads

and/or start new ones of your own. Otis left the matter as a prompt, and the OP

decided not to respond after all that time. So, don't address the OP to make a

post about which has long ago been abandoned.
