# Properties of Triangles
## Exercise 6.5
Question 1: PQR is a triangle, right angled at P. If PQ = 10 cm and PR = 24 cm, find QR.
QR^2 = PQ^2 + PR^2
Or, QR^2 = 10^2 + 24^2 = 100 + 576 = 676
Or, QR^2 = 2 xx 2 xx 13 xx 13
Or, QR = 2 xx 13 = 26 cm

# What is postselection in quantum computing?
A quantum computer can efficiently solve problems lying in the complexity class BQP. I have seen a claim the one can (potentially, because we don't know whether BQP is a proper subset or equal to PP) increase the efficiency of a quantum computer by applying postselection a... | {} |
