A chemist was tasked with removing 50mL from a 2.5L stock solution of hydrochloric acid. After completing the task, it was discovered that 2.45L of the stock solution remained. What was the chemist's percent error?

0%

Step-by-step explanation:

The chemist was tasked with removing 50mL from a stock solution of HCl acid.

Now:

After the task, it was discovered that 2.45L of the stock solution remained.

Since the volume of acid removed by the chemist is equal to the volume of what the stock solution was reduced by, his percentage error is 0%.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
