Answer:

To find the values of A and B in the equation 1 ÷ 7 - 4√3 = A + B√3, you can equate the real and imaginary parts on both sides of the equation separately.

Real Part:

1 ÷ 7 = A

Imaginary Part:

-4√3 = B√3

Now, solve for A and B:

1. Real Part: A = 1 ÷ 7 = 1/7

2. Imaginary Part: B√3 = -4√3

Divide both sides by √3:

B = -4

So, A = 1/7 and B = -4.
