If `vecA=2hati-3hatj+hatk and vecB=3hati+2hatj.` Find `vecA.vecB and vecAxxvecB`

If vecA = hati+hatj+hatk and vecB = 2hati+hatj find vecA . vecB

If veca=4hati+3hatj+2hatk and vecb=3hati+2hatk , find |vecbxx2veca|

If = veca = hati-7hatj+7hatk and vecb = 3hati-2hatj+2hatk find vecaxxvecb and |vecaxx vecb| .

If vecA=3hati+hatj+2hatk and vecB=2hati-2hatj+4hatk then value of |vecAxxvecB| will be

If vecA=9hati-7hatj+5hatk and vecB=3hati-2hatj-6hatk then the value of (vecA+vecB).(vecA-vecB) is

If veca=hati-2hatj+3hatk and vecb=2hati+3hatj-5hatk then find vecaxxvecb and verify that vecaxxvecb is perpendicular to each one of veca and vecb .

If veca=2hati-3hatj-hatk and vecb=hati+4hatj-2hatk , then vecaxxvecb is

If veca=7hati+3hatj-6hatk , vecb=2hati+5hatj-hatk and vecc=-hati+2hatj+4hatk . Find (veca-vecb)xx(vecc-vecb) .
