Question

Hi I need help with ALgebra 2 problem! Can you just give me a sec to write down the equation that would be great!

Answer 1

\[3(x+3)^{3/4}= 81\]

Answer 2

I can try I'm in 7th grade. I'm in Algebra as well. :)

Answer 3

So these are my steps I will show okay give me one sec

Answer 4

okay thanks!

Answer 5

First I divided the 3 from both sides to get rid of that number. I got
\[(x+3)^{3/4}=27\]

Answer 6

so then what I did was I did the opposite of the fraction sign.. and got
\[\left| x+3 \right|=81\]

Answer 7

and then what I did was got this as my answer

\[x+3= plus or minus 81\]

Answer 8

and then plugged 81 and -81 into x and got -78 and 84

Answer 9

but then i looked online for the answer that my techer put up and he had it without the absolute value sign but then that confused me with the rule you use

Answer 10

I have never done it that way before.....weird

Answer 11

Hm, Yeah.

Answer 12

yeah like it goes with this rule...but apparently I did it wrong but i followed the rules...

Answer 13

You needed to subtract 3 from both sides before you plug it in...

Answer 14

That is the only thing I can tell....

Answer 15

oh yeah... dude thanks!

Answer 16

Answer 17

I agree... If you don't mind may I ask for help with a question as well?
Which of the following has a graph that is a straight line?
Equation 1: y = 4x3 + 6 Equation 2: y = 5x − 4.5 Equation 3: y2 = x − 1 Equation 4: y = 2x2 + 6
I'm confused. :(
