4−(9/2)≠(√((4−(9/2))^2 )) 4−(9/2)=−(√((4−(9/2))^2 ))=−(√((5−(9/2))^2 ))=−(5−(9/2))

4−92≠(4−92)24−92=−(4−92)2=−(5−92)2=−(5−92)

generally a≠(√a^2 )=∣a∣ a=(√a^2 )=∣a∣ if a≥0 a=−(√a^2 )=−∣a∣ if a<0

generallya≠a2=∣a∣a=a2=∣a∣ifa⩾0a=−a2=−∣a∣ifa<0

a=(√a^2 )=a if a≥0 a=−(√a^2 )=−a if a<0 No need to use ∣ ∣ Am I right?

a=a2=aifa⩾0a=−a2=−aifa<0Noneedtouse∣∣AmIright?

you are right sir. I just want to say (√a^2 ) is only the absolute value of a number, but not always the number itself.
