Answer:
-2>-5
4/7<3/5
-1.3>-1.333333
Step-by-step explanation:
The scalar product, or dot product, of two vectors is the sum of the products of corresponding coordinates.
... u·v = (4, 4)·(-8, 3) = 4(-8) + 4(3) = -20
Then the product of a scalar and a vector is a vector with each of the original coordinates multiplied by the scalar.
... (u·v)v = -20v = -20(-8, 3) = (160, -60)
The answer is 243
so first it is 1/27^2/3
then you multiply
