Jackie wants to create a scale drawing of the poster shown below: a rectangle is shown. the length of the rectangle is labeled 4 feet. the width of the rectangle is labeled 8 feet. what are the dimensions of the poster at one-half its current size? 8 ft by 16 ft 8 ft by 12 ft 2 ft by 4 ft 4 ft by 4 ft

its 2ft to 4 ft because half 8 is 4 and half 4 is 2, plus I took the test and it was right.

Step-by-step explanation:

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)
