\(145\times97+145\times2+145\)
\(=145\times\left(97+2+1\right)\)
\(=145\times100\)
\(=14500\)
145x97+145x2+145
=145x97+145x2+145x1
=145x(97+2+1)
=145x100
=14500
145 x 97 + 145 x 2 + 145
\(= 145 \times \left(\right. 97 + 2 + 1 \left.\right)\)
\(= 145 \times 100\)
\(= 14500\)
Ta có :
` 145 xx 97 + 145 xx 2 + 145 `
` = 145 xx 97 + 145 xx 2 + 145 xx 1 `
` = 145 xx ( 97 + 2 + 1 ) `
` = 145 xx 100 `
` = 14500 ` .
