3.c. 2.d. 11.3.......
1. If f(x)= 16^1/3 and g(x)=2x^-2/5
what is f(x) * g(x)

What is f(x)/g(x)

2. The Volume of a sphere can be given by the V= 4.18879r^2. You have to design a spherical container that will hold a volume of 50 cubic inches. What should the radius of your container be?

A. 2.29

b. 3.45

c. 2.43

d. 11.94

3. A lunch menu consists of 3 different kinds of sandwiches, 3 different kinds of soup, and 5 different drinks. How many choices are there for ordering a sandwich, a bowl of soup, and a drink?

A. 11

b. 45

c. 4320

d. 3

-
1) f(x) = (2^4)^1/3 = 2^4/3 g(x) = 2^-2/5 ==> f(x)g(x)= 2^14/15

2) 50 = 4.19r^2 ==> r = 3.45

3) 3*3*5 = 45
