O.2 0.2 0.2 the answer is 0.2
yeah
To simplify
we need to use the fact that
Why the absolute value? It's because .
We start by rewriting as
Since , we have , and the above reduces to
Then we pull out any 4th powers under the radical, and simplify everything we can:
where allows us to write , and this also means that . So we end up with
making the last option the correct answer.
The first one is 23/30 and the second one is 2 19/24
-24=u/6 just times 6 to both sides -24*6=-144 rewrite
-144=u
Hope this helps have a nice day
