z is inversly proportional to r then z = k/r
zr = k
If z = 32 when r = 1.5
32(1.5) = k
48 = k
k = 48
If z = 8 then r = ?
8r = k
8r = 48
Divide to each side by 8.
r = 48/8
r = 6

<h3>Explanation:</h3>
(16^4 -2^13 -4^5) mod 11 = ((2^4)^4 -2^13 -(2^2)^5) mod 11
= (2^16 -2^13 -2^10) mod 11
= (2^10 mod 11)·((2^6 -2^3 -1) mod 11)
= (1024 mod 11)·(55 mod 11)
= 1 · 0 = 0
When the sum shown above is divided by 11, its remainder is zero. Hence the sum is divisible by 11.
