giúp mik với. mik cần gấp lắm

Answer 1

\(35\cdot34+70\cdot38+65\cdot75+65\cdot35\)

\(=35\cdot34+35\cdot76+65\cdot\left(75+35\right)\)

\(=35\cdot\left(34+76\right)+65\cdot110\)

\(=35\cdot110+65\cdot110\)

\(=110\cdot\left(65+35\right)\)

\(=110\cdot100=11000\)

Answer 2

35 . 34 + 70 . 38 + 65 . 75 + 65 . 35

= 35 . 34 + 35 . 76 + 65 . 75 + 65 . 35

= 35 . (34 + 76) + 65 . (75 + 35)

= 35 . 110 + 65 . 110

= 110 . (35 + 65)

= 110 . 100

= 11000

~Std well~

Answer 3

\(35\cdot34+70\cdot38+65\cdot75+65\cdot35\)

\(=35\cdot34+35\cdot76+65\cdot75+65\cdot35\)

\(=35\cdot\left(34+76\right)+65\cdot\left(75+35\right)\)

\(=35\cdot110+65\cdot110\)

\(=110\cdot\left(35+65\right)\)

\(=110\cdot100=11000\)

Answer 4

\(35.34+70.38+65.75+65.35=\)\(35\left(34+2.38\right)+65.\left(75+35\right)\)

\(=35.90+65.110=10300\)
