If u is odd and w is even, what is `(uw)^(2)+u`?

If u is even and w is odd, what is u+uw ?

If u+t=5 and u-t=2 , what is the value of (u-t)(u^2-t^2) ?

If u : v : w = 3 : 6 : 8, then what will be the ratio of (u/v) : (v/w) : (w/u)?

Let u,v,w be such that |u| = 1, |v| = 2, |w| = 3. If the projection v along u is equal to that w along u and v,w are prependicular to each other then |u - v + w| =

If 3u+w=7 and 3k-9u=2, what is the value of w+k?

u : v = 4 : 7 and v : w = 9 : 7. If u = 72, then what is the value of w ?
