Answer:
9x4=36
Step-by-step explanation:
36/54 = x/100
54x = 100 * 36
54x = 3600
x = 3600 ÷ 54
x = 66.666666.... so 66.67
First put it into a proportion and then cross multiply. After that you divide both sides by 54 to get x alone which gives you 66.66666 which is rounded to 66.67
Answer: 66.67%
We can rewrite the expression under the radical as
then taking the fourth root, we get
Why the absolute value? It's for the same reason that
since both and return the same number , and captures both possibilities. From here, we have
The absolute values disappear on all but the term because all of , and are positive, while could potentially be negative. So we end up with
