The rule we use here is
If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)
We subtract the exponents when dividing exponentials like this. The bases must be the same.
So this means the exponents 13 and 3 subtract to get 13-3 = 10
We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.
Here, Circumference = Diameter * π
C = 3.14 * 7.5
C = 23.55
Now, Number of strings = 23.55 / 1.45 = 16.24
In short, He needs approx. 16 strings
Hope this helps!
