Answer :

The difference in magnitudes between the stars can be found using the formula Δm = m1 - m2. Where m1 = magnitude of star A, m2 = magnitude of star B, and Δm is the difference in magnitudes.

Given that Star A has a magnitude of 4 and Star B has a magnitude of 6. Therefore,Δm = 4 - 6= -2.

The negative sign indicates that star B is brighter than star A.

Thus, to find out how much brighter Star A is than Star B, we need to take the antilogarithm of Δm/2.5.

This can be calculated as follows:antilog (-2/2.5)= antilog (-0.8) = 0.1585.

The antilogarithm is approximately equal to 0.16.

Therefore, Star A is 0.16 times brighter than Star B. Answer: The brightness ratio between Star A and Star B is 0.16.
