(2x4)^ 2 -3x(5+3)

OpenStudy (anonymous):

What are you trying to do with this expression. It is not an equation yet.

OpenStudy (anonymous):

(2x4)the exponent 2

OpenStudy (anonymous):

(2x4)2^

OpenStudy (anonymous):

\[(2\times4)^{2}-3x(5+3) ?\]

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

4x4because is ^

OpenStudy (anonymous):

P.E.M.D.A.S

OpenStudy (anonymous):

Hero I need an explanation not the answer

OpenStudy (anonymous):

Work thru the ( ) first. What do you get?

OpenStudy (anonymous):

My result is 8

OpenStudy (anonymous):

remember to follow the pemdas rules

OpenStudy (anonymous):

and the other one?

OpenStudy (anonymous):

Then distribute the -3x and the exponent

OpenStudy (anonymous):

Yes 16*2=32

OpenStudy (anonymous):

5+3=8 so 32*24

OpenStudy (anonymous):

P: parenthesis E: exponent M: multiplication D:division A: addition S: subtraction

OpenStudy (anonymous):

Try again you have\[8^{2}-3x(8)\]

OpenStudy (anonymous):

(2x4^2) -3*(5+3) 2*16=32. 5+3=8 32-24=8

OpenStudy (anonymous):

the four itself in the first equation is not squared. 2 times 4 is

OpenStudy (anonymous):

Because you * 8x3

OpenStudy (anonymous):

We all still don't know what the original equation is then. Please use * for multiplication and be sure to use ( ) whenever possible.

OpenStudy (anonymous):

but I think you are getting it

OpenStudy (anonymous):

Basically what The table said

OpenStudy (anonymous):

The order of the equations it was a little confused

OpenStudy (anonymous):

for the future... Do whats in the ( ) first. Then if there are any powers they are next. From left to right, do division or multipliction, whatever comes first, they are the same priority. Last, from left to right, do addition and subtraction again they have the same priority.

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

Thanks
