55=2(5D)^1/2
55/2=(5D)^1/2
(55/2)^2=5D
(55/2)^2/5=D
^ means to the power of, the last one reads "55 over 2 all to the power of 2 all over 5 equals D"

55=2*(square root of 5D)
first divide by 2
27.5=square root of 5D
square both sides
756.25=5D
divide by 5
151.25=D

55=2*5d^1/2
55/2=5d^1/2
27.5^1/2=5d
5.24=5d
5.24/5=d
1.048=d

The entire problem is simple algebra:
2sqrt(5d) = 55
sqrt(5d) = 27.5
sqrt(5d^2) = 27.5^2
5d = 756.25
d = 151.25
