The answer is
. I've demonstrated the 'split and combine' method in the image attached.
This principal is based on the fact that you can multiply and divide radicals as you would with regular integers, but you remember that the answers remain as radicals unless the number you're dealing with is a square (e.g. 9, 16, 25).

Answer:
0.9689
Step-by-step explanation:
Given:
banks in Switzerland are private organizations, p = 51% = 0.51
Sample size, n = 544 banks
To find:
Probability (the sample proportion of private banks will be greater than 47%)
Now,
Mean of the sample, μ = np = 544 × 0.51 = 277.44
= 544 × 0.47 = 255.68
Standard deviation =
or
Standard deviation =
or
Standard deviation = 11.6595
Now,
=
=
=
=
Now, from standard z value table, we get
= 1 - 0.031021
= 0.9689
