Acity has a population of 380,000 people. suppose that each year the population grows by 6.25 % . what will the population be after 8 years? round to the nearest whole number.

570,000

Step-by-step explanation:

Change the % to decimal.

0.0625 = 6.25%

Now find how much 6.25% of 380,000 is.

0.0625 x 380,000 = 23,750

so The population increases by 23,750 people each year. but we need 8 years, so...

23,750 x 8 = 190,000

Now add that to the current population..

380,000 + 190,000 = 570,000

570,000

Hope this helped! Please mark as brainliest! Thanks!

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)
