-2pi greater than -3pi
Consider pi as a common , now compare (-2) and ( -3)
On a number line, numbers always increase (become "more positive") to the right and decrease (become "more negative") to the left.
so, (-2) is always on the right of (-3) sp. (-2) is greater tahn (-3)
Thus, (-2 ) > ( -3)
So, (-2)pi > (-3) pi
Answer : (-2)pi > (-3) pi
