Homework Statement
Given that 0 <or equal to a <or equal to b, show that
a <or equal to sqrt(ab) <or equal to (a+b)/2 <or equal to b
The number sqrt(ab) is called the geometric mean of a and b
Homework Equations
Not sure -_-
The Attempt at a Solution
a = sqrt(aa) <or equal to sqrt(ab) <or equal to sqrt(bb) = b
a = (a+a)/2 <or equal to (a+b)/2 <or equal to (b+b)/2 = b
Not sure what to do now -_-
