Hurry up! Square root problem of seventh grade mathematics
1. That is, √(x-4)+√(4-y)=0, while √(x-4)≥0, ∴x-4=4-y=0, √.

2. Because the two square roots of m are reciprocal relations, we can know that 3a-22 and 2a-3 are reciprocal relations, then we can list the equation: 3a-22=-(2a-3), from which we can get that a=5, then 3a-22=-7 and 2a-3=7, then m is equal to the square of 2a-3.
