73+3(23−13)2

dude:

Is the two after an exponent?

hallm:

it is suopsed to be 7/3 + 3 (2/3 - 1/3) ^2 the two is the exponent

dude:

\(\large \frac73 + 3 (\frac23 - \frac13) ^2\)

hallm:

yes

dude:

Use PEMDAS

dude:

First start out with parenthesis

hallm:

i dont know how to divide fractions

dude:

No no, just combine them aka do \( \frac23 - \frac13\)

hallm:

ohhh ok

dude:

Yes, so what is \(\frac23 - \frac13) \)?

hallm:

1/3

mikewwe13:

my mistake

dude:

Right

dude:

So we have \(\frac73 + 3 ( \frac13) ^2\)

dude:

Exponents is next

dude:

so do \(\frac13 ^2\)

hallm:

ok

hallm:

0.111

dude:

Sure, you didnt have to simplify it like that Now just multiply 0.111 by 3

hallm:

0.333

dude:

Now add 0.333 and \(\frac73\)

hallm:

2.666333

hallm:

or 2.6

dude:

That is your answer, is it asking in decimal or fraction form?

hallm:

it just says put your answer in the box

dude:

oh then I guess that should be fine though it is recommended you do it in fraction form

hallm:

how would i do that

dude:

I will redo the steps we did without the decimals, if you have questions just ask :P \(\frac73 + 3 (\frac23 - \frac13) ^2\) =>\(\frac73 + 3 (\frac13) ^2\) Do exponents (\(\frac19=0.111)\) \(\frac73 + 3 (\frac19)\) Multiply 3 \(\frac73 + \frac13\) =>\(\frac83\)

hallm:

wooooowwww your really good at math

dude:

Haha
