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

The ans is a = 9 b = 4

a=9 b=4 √4+9=11 √9+4=7

a=9 , b=4 so 9 is divisible is 3 so 3+4=7 ans 4 is divisible by 2 so the 4 root is 2 or 2+9=11

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 abcde=1 (where a,b,c,d and e are all positive real numbers) then what is the minimum value of a+b+c+d+e?
