\(\dfrac{63^3-37^3}{26}+\dfrac{63}{37}\)
\(=100+2\cdot63\cdot37+\dfrac{63}{37}\)
\(=\dfrac{176257}{37}\)
\(\dfrac{63^3-37^3}{26}+\dfrac{63}{37}\)
\(=100+2\cdot63\cdot37+\dfrac{63}{37}\)
\(=\dfrac{176257}{37}\)
a) 28 + 55 = 83
45 + 49 = 94
37 + 53 = 90
b) 61 - 18 = 43
53 - 26 = 27
92 - 84 = 8

15+24+37+26+35+63
=(15+35)+(24+26)+(37+63)
=50+50+100
=100+100
=200
0,37 + 37/50 + 26% + 63/100
= 37/100 + 37/50 + 13/50+ 63/100
= ( 37/100 + 63/100 ) + ( 37/50+ 13/50 )
= 1 + 1
= 2
37 + 92 - 36 + 63 - 744 = 129 - 36 + 63 - 744
= 93 + 63 - 744
= 156 - 744
= -588
là -588
k cho mk nha
