Answer:
true when a=0 or b=0
Explanation:
You want the solution to √a +√b = √(a+b).
Solution
Squaring both sides of the equation gives ...
a +2√(ab) +b = a +b
Subtracting (a+b) from both sides, we have ...
2√(ab) = 0
ab = 0 . . . . . . . divide by 2 and square
By the zero product rule, this product can be zero if and only if at least one of the factors is zero.
a = 0 or b = 0
√a +√b = √(a+b) only if at least one of 'a' or 'b' is zero.
