\(59\cdot73-30^2+27\cdot59\)

\(=59\left(73+27\right)-900\)

\(=5900-900\)

\(=5000\)

59.73-30^2+27.59=59(73+27)-30^2=59.100-30^2=5900-900=5000

     \(2x+5=3^4-3^2 \)

⇔\(2x+5=9\)

⇔\(2x=4\)

⇔\(x=2\)

59.73-30²+27.59

0,6 giờ

phân số nhé

36 phút =...3/5=0,6.. giờ( lấy 36:60)

Ta có:

\(x^3-27-9\left(x-3\right)=\left(x-3\right)\left(x^2+3x+9\right)-9\left(x-3\right)\)

\(=\left(x-3\right)\left(x^2+3x+9-9\right)=\left(x-3\right)\left(x^2+3x\right)\)

\(=\left(x-3\right)\left(x+3\right)x=x\left(x^2-9\right)\)

(x^3-27)-9(x-3)=x(x^2-9)

<=>(x-3)(x^2+3x+9)-9(x-3)-x(x-3)(x+3)=0

<=>(x-3)(x^2+3x-x(x+3) )=0

<=>(x-3)(x^2+3x-x^2-3x)=0

<=>(x-3)=0

<=>x=3

bn tách ra là đc nhá
(x^3-27)-9(x-3)
=x^3-27-9x+27
=x^3-9x
rút x ra
=x(x^2-9)

59 . 73 - 30² + 27 . 59

= 59 .(73 + 27) - 30²

= 59 . 100 - 30²

= 5900 - 900

= 5000

= 59 . ( 73 + 27 ) - 30² 

= 59 . 100           - 900

= 5900 - 900 

= 5000 

= 5k ( mua được nửa ly trà sữa ) 

59.73-30²+27.59

=4037-30²+1593

=3137+1593

=4730

cảm ơn

59.73-30^3+27.59
=59(73+27)-900.30
=59.100-270.100
=100(59-270)
=100.(-211)
=-21100(tick cho mk nha bn)
