Javob: 10000
Berilgan ifodani $37\cdot 59+37\cdot 41+63\cdot 59+41\cdot 63$ guruhlab, umumiy koeffitsientni ajratamiz:
\[
37\cdot 59+37\cdot 41+63\cdot 59+41\cdot 63
=37(59+41)+63(59+41).
\]
Endi qavs ichidagi yig‘indini hisoblaymiz: $59+41=100$.
Shu bilan ifoda $37\cdot100+63\cdot100= (37+63)\cdot100 =100\cdot100=10000$ ga teng bo‘ladi.
Demak, to‘g‘ri javob **B) 10000**.
