Suppose a and b are real numbers such that:

a√a + b√b = 183 b√a + a√b = 182

What is the value of (9/5)(a + b)?

If a and b are real numbers that satisfy the equation below, what is the value of a and b respectively?

Give positive numbers a, b and c are such that ab + bc + ca + abc = 4, What is the value of 1/a+2 + 1/b+2 + 1/c+2 = ?
