Question

state whether - 1 + root 2 lies in the negative or positive side of number line​

Answer 1

method 1:

√2=1.414

so

-1+1.414=0.414

therefore it lies on the positive side of number line

method 2:

as √2 > 1

therefore

-1+√2 > 0

hence the expression -1+√2 lies on the positive side of number line.
