is that raised to 0.66?
OpenStudy (anonymous):
(x-2)^2/3 = 49
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
cuberoot((x-2)^2) = 49
OpenStudy (anonymous):
can you answer that now?

I'm not that good at math so I'm going to say no. haha
OpenStudy (anonymous):
\[\sqrt[3]{(x-2)^2} = 49\]
OpenStudy (anonymous):
to answr this, you must try to look on how you will be able to make the left hand side look similar to the right hand side
OpenStudy (anonymous):
clue: \[\sqrt[3]{(x-2)^2} \] is also equal to
OpenStudy (anonymous):
\[(\sqrt[3]{x-2})^2\]

see something to work with?
OpenStudy (anonymous):
dude, lol I am just not even understanding this right now. My math class starts in like 15 minutes. Is there an easier way to explain?
OpenStudy (anonymous):
\[(\sqrt[3]{x-2})^2 = 49\]
OpenStudy (anonymous):
49 is also equal to???
OpenStudy (anonymous):
sorry, i can't say the answer directly. rules. hehhee

try manipulating 49
OpenStudy (anonymous):
to MAKE IT LOOK SIMILAR TO THE LEFT HAND SIDE
OpenStudy (anonymous):
Hey, don't yell. Haha I understand tho. I really appreciate your help! Let's be friend ;)
OpenStudy (anonymous):
I'm not yelling. I just wanted to emphasis that statement
OpenStudy (anonymous):
in what ways can you make 49 look somewhat simalar to the left hand side?

I know, I'm just trolling you lol
OpenStudy (anonymous):
But I really do need the help so yeah.
OpenStudy (anonymous):
we all know that 49 is a perfect square, right?
OpenStudy (anonymous):
yeah... 7
OpenStudy (anonymous):
so???
since there's \[(\sqrt[3]{x-2})2\]

and there's 7^2
OpenStudy (anonymous):
what will you do now?
OpenStudy (anonymous):
if the exponents of 2 terms in an equality are the same, then they are equal to each other. You can just remove the ^2
OpenStudy (anonymous):
that leaves you where?
OpenStudy (anonymous):
so just 7? Man, this would be easier if I was talking to you face to face haha

OpenStudy (anonymous):
yes and how bout the left side?
OpenStudy (anonymous):
you have just removed the right side's exponent only
OpenStudy (anonymous):
you have just removed the right side's exponent only
\[\sqrt[3]{x-2} = 7\]
OpenStudy (anonymous):
Are you getting this?
OpenStudy (anonymous):
Kind of... I'm following you a bit. Welp, math class is about to start so, lol I guess I'll keep in touch?

just make sure to isolate x from all the constants
