When is the magnitude of A plus B equal to the magnitude of A B?

a + b = ab
a = ab - b = b(a - 1)
b = a / (a-1)
Any pair of numbers that satisfy that equation,
e.g. a = 3, b = 1½ . . . because 3 + 1½ = 4½ and 3 x 1½ = 4½
another example: a = 101, b = 1.01 because
101 + 1.01 = 102.01,
and 101 x 1.01 = 102.01

The magnitude is 738 kJ/mol.
What do electrons have that protons always have in equal magnitude?
Charge
What offsets an action force?
A force of equal magnitude, acting in the opposite direction.
Does a tsunami have magnitude?
There are Magnitude scales for Tsunamis, but you have to be a maths wizz to work them out, using the formula Mt = a log h + b log R = D.
What must be the relationship between two vectors a and b if the magnitude of vector a plus b is equal to magnitude of a-b?
a and b must face in opposite directions.
When magnitude of vector a plus b is equal to the magnitude of vector a minus b then what is the angle between two vectors a and b?
2pi/3 radian or equivalent 120 degree
If is added to under what conditions does the resultant vector have a magnitude equal to A B?
1. When the two vectors are parlell the magnitude of resultant vector R=A+B. 2. When the two vectors are having equal magnitude and they are antiparlell then R=A-A=0. For more information: thrinath_dadi@yahoo.com
What does b plus a plus b-a equal?
b + a + b - a = 2b
If vector B is added to vector A under what circumstances does the resultant vector A plus B have magnitude A plus B. under what circumstances does the resultant vector equals to zero?
if b + a , since a+b equals b + a due to it being commutative . it shud have the same magnitude and direction
Two vectors A and B have precisely equal magnitude for the magnitude of A - B to be 100 times larger than the the magnitude of what must be the angle between them?

What does b plus b equal?
2b
How a plus b is equal to a-b?
If a = 2b
Suppose vector equation A plus B equals 0.how does the magnitude of B compare to that of A?
B could be either greater than, lesser than or equal to A. 7 +(-7) = 0 (-7) = 7 = 0 0 + 0 = 0
If A plus B equals 0 than what can you say about the components of the two vectors?
The components of these vectors will be equal in magnitude but opposite in direction. This can be proved as follows.If A+B=0 then A=-BOr Axi+Ayj+Azk=-(Bxi+Byj+Bzk)Comparing the co-efficients of i, j, kAx=-Bx Ay=-By Az=-BzThis shows that components of A and B are equal in magnitude to each other but are opposite in direction.
If the magnitude of the product A x B is equal to AB then?
Then, if A nd B are scalars, it is not really surprising. If A and B are vectors then they have the same direction.
What does a squared plus b squared equal?
(a+b)(a+b)Also equal to a2+2ab+b2
