B is the answer to this problem
It’s the bottom left answer because the angles are opposite of each other. They are also congruent. I hope this helps!
(a-b) X (a+b)
= aXa - bXa +aXb -bXb (distributing)
Now, cross product of a vector with itself = 0
so, aXa = 0, bXb = 0
Also, aXb = - bXa
so,
(a-b) X (a+b) = 0 + aXb + aXb + 0
= 2aXb
hence, proved :)
Answer:

Step-by-step explanation:
We need to move the decimal so there is only one zero to the left of the decimal point. Since the decimal is being moved to the right, it is a negative exponent.
