a) \(36\times532+64\times532\)
\(\Rightarrow532\times\left(36+64\right)\)
\(\Rightarrow532\times100\)
\(\Rightarrow53200\)
b) \(245\times327-245\times26-245\)
\(\Rightarrow245\times\left(327-26-1\right)\)
\(\Rightarrow245\times300\)
\(\Rightarrow73500\)
36 x 532 + 64 x 532
= 532 x ( 64 + 36 )
= 532 x 100
= 53200
