Ineed on the back of this worksheet

For #11 the answer is $58.14

Step-by-step explanation:

To find the value of anything with a sales tax simply multiply the cost by the tax.

$57 * 2%

$57 * .02

$1.14

Now that we have the sales tax, add it to the original cost.

$57 + $1.14 = $58.14

You can do this for each of the sales tax problems.

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)
