96 * 37 - 3 * 26 * 32 - 96
= 96 * 37 - 96 * 26 - 96 * 1
= 96 * ( 37 - 26 - 1 - 1 )
= 96 * 10
= 960
=
96 x 37 - 3 x 26 x 32 - 96
= 3552- 3 x 26 x 32 - 96
= 3552 - 78 x 32 -96
= 3552 - 2496 -96
= 1056 - 96
= 960

=\(\frac{64\cdot100}{96\cdot150}=\frac{2^8.5^2}{2^6.3^2.5^2}=\frac{2^2.1}{1.3^2.1}=\frac{4}{9}\)

45 x 77 + 9 x 22 x 5 + 45
= 45 x 77 + 45 x 22 + 45
= 45 x (77 + 22 + 1)
= 45 x 100
= 4500

a) 54x113+45x113+113 b)117x(36+62) -17x(62+36)
=(54+45+1)x113 =117x98-17x98
= 100x113 =(117-17)x98
= 11300 =100x98
=9800
a,54 x 113 + 45 x 113 + 113
=(54 + 45 +1) x 113
=100 x 113 = 11300
