Joe is 6 feet tall and took a photo of himself beside a statue this summer while visiting Rome. In the picture the Statue is 6 inches tall and Joe is 4.5 inches tall. How tall is the statue in feet.

8 ft

Step-by-step explanation:

Since we are given the size of image and actual object, we need to know the magnification factor. In this case, the man is 6ft but his image is 4.5 inches. Similarly, the statue's height is not given but in the imave it is 6 inches. If 6 ft translates to 4.5 inches then we want to know what translated to 6 inches. We apply the cross multiplication.

6 ft= 4.5inch

X ft=6 inch

X=6 ft* 6 inch/4.5 inch=8 ft

Therefore, the statue is actually 8 ft tall.

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)
