√a+√bPlease give solution |
|
Answer» Answer: Assume x=√a+√b Square in both sides: x^2 = <√a+√b>^2 Expand the RIGHT hand side of the equation. That will GIVE you x^2 = a + b + 2( √ab) X will be the square ROOT of the expression on the right. I have assumed that a and b are POSITIVE whole numbers. You can check this out by substitution of values for a and b. Let's take a = 25 and b = 4. √a + √b = 7. 25+4+ 2(√100) = 49. √49 = 7 |
