OpenStudy (jazzyfa30):

@GoldPhenoix I got another question for you so get ready for your medal

OpenStudy (jazzyfa30):

@GoldPhenoix 3[4 -2(3-2^3) +7]

OpenStudy (jazzyfa30):

okay this problem is open to anyone I just need help

OpenStudy (jazzyfa30):

By the way I got 29 but it was wrong.

OpenStudy (goldphenoix):

\[\large \large 3[4 -2(3-2^3) +7]\] For this problem, you want to do PEMDAS. So first which one do you want to do? Do you want to do, " ( )" or " [ ] " Well you HAVE to do the " ( )" because it's in a parenthesis, "[ ]" (If that make sense) So let see. 3-2^3. 2^3 is equal to 8. 3-8 is -5. So your equation should look like: \[\large \large 3[4-2\times (-5) + 7]\] Now we still have to do 2 x -5 because it's in the bracket, and it goes first before the addition. -2 multiply by -5 is 10. Your equation should look like: \[\large \large 3[4+10 + 7]\] Nowe just add up everything in the bracket: 4 + 10 + 7 is 21. 21 x 3 is 64. So your answer is: 64. I hope this help! Let me check my answer in a moment.

OpenStudy (goldphenoix):

Wow. I mest up at the end. 21 x 3 is 63. My bad.

OpenStudy (jazzyfa30):

okay I got another one for you but I'm going to close this one so I can give you your trophy.

OpenStudy (goldphenoix):

Okay. :)
