Help, please?

OpenStudy (xxmuslimxx):

The next step in simplifying this expression is to divide 40 by 4.

jimthompson5910 (jim_thompson5910):

what is the full question/problem?

OpenStudy (xxmuslimxx):

Does that link take you anywhere?

jimthompson5910 (jim_thompson5910):

yes I see it. One second

OpenStudy (xxmuslimxx):

Ok.

jimthompson5910 (jim_thompson5910):

are you familiar with PEMDAS?

OpenStudy (xxmuslimxx):

Yes.

OpenStudy (xxmuslimxx):

The question asks T or F

OpenStudy (anonymous):

need some help?

OpenStudy (xxmuslimxx):

Is the next step to solving this equation to divide 40 by 4.

OpenStudy (xxmuslimxx):

Yes, please.

jimthompson5910 (jim_thompson5910):

what does PEMDAS stand for @XxMuslimxX

OpenStudy (anonymous):

alright so it is 40/4(3)^3 right?

OpenStudy (xxmuslimxx):

Parenthesis, Exponents, Multiplication or Division, Addition or Subtraction.

OpenStudy (xxmuslimxx):

Yes...

jimthompson5910 (jim_thompson5910):

good

jimthompson5910 (jim_thompson5910):

so the first thing you do is parenthesis after that is exponents

jimthompson5910 (jim_thompson5910):

there's not much to do with parenthesis, so we move onto exponents 3^3 = ???

OpenStudy (anonymous):

oh haha jims got this.. ill be on stand by for the moment

jimthompson5910 (jim_thompson5910):

you're fine @atreyu6s3x6 go ahead and continue what you're writing

OpenStudy (xxmuslimxx):

Well, it doesn't ask to solve the problem....

OpenStudy (xxmuslimxx):

The problem asks me if dividing 40 by 4 the next step.

OpenStudy (anonymous):

wait well what is the entire question? @XxMuslimxX

OpenStudy (xxmuslimxx):

The next step in simplifying this expression is to divide 40 by 4. True, or False?

OpenStudy (xxmuslimxx):

It's False, right?

OpenStudy (anonymous):

correct its false due to PEMDAS

jimthompson5910 (jim_thompson5910):

well if you follow PEMDAS explicitly, then P comes first. P for parenthesis. There's nothing to do with parenthesis E comes next, E for exponents. We compute 3^3 to get 27 so the next step should be turning 3^3 into 27. The division part comes later
