value of
at x=8 is
.
<u>Step-by-step explanation:</u>
here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or ,
where x=8 . Let's find out:
⇒ 
Putting x =8 :
⇒ 
Splitting 8 to power 4 into 8 to power 2 ( 2 times )
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , value of
at x=8 is
.
I’m a little confused by the question and the problem, is there a picture of the problem you could add?
-2(4x-1)=5+7
(4x-1)=12/-2
4x=-6+1
x=-5/4
