1) If \( z = \frac{ \left\{ \sqrt{3} \right\}^2 - 2 \left\{ \sqrt{2} \right\}^2 }{ \left\{ \sqrt{3} \right\} - 2 \left\{ \sqrt{2} \right\} }\) find \(\lfloor z \rfloor.\)

2) If \(\lceil x\rceil+\lfloor x\rfloor+x=4.8\) find x.

1) do the braces mean ceiling or fractional part or neither?

 

2) clearly x = z + 0.8

 

a little tinkering shows x = 1.8

 

2 + 1 + 1.8 = 4.8

I think the guest meant {} as fractional part
