is represented square root as @ then wouldnt -@100 equal both -10 and 10?
because @100 equals -10 and 10 so if i multiplied both with - the awnsers would still be -10 and 10 just switched around respectively
I would guess that if a sign is specified, they mean take the negative square root. example: \[ - \sqrt{4} = -2 \]
It comes down to, what did the writer mean ?
ok what if i did it like this -(\[\sqrt{100}\])
i mean -(\[\sqrt{100}\])
if they wanted you to consider both roots, it would be clearer to write \[ ± \sqrt{100} \] if they don't write that, but rather \[ - \sqrt{100} \] I would interpret the second way to mean "take only the negative root"
ok thank you
It helps to know the context of the expression. Whoever wrote this should be trying to be clear (as opposed to confusing).
