1. a particular shade of orange paint has 2 cups of yellow

paint for every 3 cups of red paint. on the double number

line, circle the numbers of cups of yellow and red paint

needed for 3 batches of orange paint.

6 cups of yellow paint and 9 cups of red paint are required for 3 batches of orange paint.

Step-by-step explanation:

Consider the provided information.

A particular shade of orange paint has 2 cups of yellow  paint for every 3 cups of red paint.

We need to find the numbers of cups of yellow and red paint  needed for 3 batches of orange paint.

For one batches of orange paint we need 2 cups of yellow and 3 cups of red.

So for 3 batches of orange paint we need:

2×3 = 6 cups of yellow paint.

3×3 = 9 cups of red paint.

The required number line is shown below.

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)
