A forest covers 69,000 acres. A survey finds that 0.6% of the forest is old-growth trees. How many acres of old-growth trees are there?

414 acres.

Step-by-step explanation:

To answer this question we have to multiply the percent by the total acres.

Remember that when multiplying percents we have to move the decimal 2 places to the left.

So, the equation looks like this:

Therefore, there are 414 acres that are old-growth trees.

We can check our answer by dividing 414 by 69,000.

414/69000 = .006

.006 * 100 = .6

I hope this helps!!

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)
