\(\dfrac{63^3-37^3}{26}+\dfrac{63}{37}\)
\(=100+2\cdot63\cdot37+\dfrac{63}{37}\)
\(=\dfrac{176257}{37}\)
\(\dfrac{63^3-37^3}{26}+\dfrac{63}{37}\)
\(=100+2\cdot63\cdot37+\dfrac{63}{37}\)
\(=\dfrac{176257}{37}\)
56. 64 = ( 60 - 4 )( 6 0 + 4 ) = 60^2 - 4^2
= 3600 - 14
= 3584
\(56^2+44^2+2.44.56\)
\(=\left(56+44\right)^2\)
\(=100^2=10000\)
a) \(56^2+44^2+2.56.44=56^2+2.56.44+44^2=\left(56+44\right)^2=100^2=10000\)
b) \(36^2+64^2+72.64=36^2+2.36.64+64^2=\left(36+64\right)^2=100^2=10000\)
c) \(136^2+36^2-72.136=136^2-2.36.136+36^2=\left(136-36\right)^2=100^2=10000\)
a) $56^2+44^2+2.56.44=56^2+2.56.44+44^2=\left(56+44\right)^2=100^2=10000$562+442+2.56.44=562+2.56.44+442=(56+44)2=1002=10000
b) $36^2+64^2+72.64=36^2+2.36.64+64^2=\left(36+64\right)^2=100^2=10000$362+642+72.64=362+2.36.64+642=(36+64)2=1002=10000
c) $136^2+36^2-72.136=136^2-2.36.136+36^2=\left(136-36\right)^2=100^2=10000$
\(\frac{63^3+13^3}{76}-13.63\)
\(=\frac{\left(63+13\right)\left(63^2-63.13+13^2\right)}{76}-13.63\)
\(=\frac{76\left(63^2-63.13+13^2\right)}{76}-13.63\)
\(=\left(63^2-63.13+13^2\right)-13.63\)
\(=63^2-2.13.63+13^2\)
\(=\left(63-13\right)^2=50^2=2500\)
=7.8+7.9
=7. (8+9)
=7.17
