√3÷16\24

√3/4

I don't know what operation "\" is, but if you meant "/" then

√3÷16/24 = √3384
or,
√3÷(16/24) = √3 * 24/16 = 3√3/2
or, maybe you meant
√(3/16)/24
who knows? Parentheses are important when typing online.
Remember, It's not my job to figure out what you mean.
It's your job to say it so clearly you cannot be misunderstood.
