Answer:
1.2
The first step would to be to plug in your numbers for your variables, so
ab/bc= (6)(0.9)/(0.9)(5)
(6)(0.9)/(0.9)(5)
6*0.9=5.4
0.9*5=4.5
5.4/4.5=1.2

Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²
