\(26\times8+4\times13-10\times26\)
\(=26\times8+2\times2\times13-10\times26\)
\(=26\times8+2\times26-10\times26\)
\(=26\times\left(8+2-10\right)\)

\(4\times26\times25=\left(4\times25\right)\times26=100\times26=2600\\ 63\times78-53\times78=\left(63-53\right)\times78=10\times78=780\\ 67\times92+67\times8=67\times\left(92+8\right)=67\times100=6700\\ 8\times23\times25\times125=\left(8\times125\right)\times\left(23\times25\right)=1000\times575=57500\)
a) 13 x 5 x 2
= 13 x (5 x 2)
= 13 x 10 = 130
5 x 2 x 34
= (5 x 2 ) x 34
= 10 x 34 = 340
b) 2 x 26 x 5
= 26 x (2 x 5)
= 26 x 10 = 260
5 x 9 x 3 x 2
= (9 x 3) x (5 x 2)
= 27 x 10 = 270
= 13 x 2 x 8 + 4 x 13 - 10 x 2 x 13
= 13 x 16 + 4 x 13 - 20 x 13
= 13 x (16 + 4 - 20)
= 13 x 0
= 0
26 x 17 + 38 x 26 + 26 x 44 + 26
= 26 x 17 + 38 x 26 + 26 x 44 x 1
= 26 x ( 17 + 38 + 44 + 1 )
= 26 x 100
= 2600
Chúc bạn học tốt !!!
\(\dfrac{26}{7}\) x \(\dfrac{11}{3}-\dfrac{26}{7}\) x \(\dfrac{2}{3}-\dfrac{6}{3}\) x \(\dfrac{26}{7}\)
\(=\dfrac{26}{7}\) x \(\left(\dfrac{11}{3}-\dfrac{2}{3}-\dfrac{6}{3}\right)\)
\(=\dfrac{26}{7}\) x \(\dfrac{3}{3}\)
\(=\dfrac{26}{7}\) x \(1=\dfrac{26}{7}\)
26/7 x 11/3 - 26/7 x 2/3 - 6/3 x 26/7
=( 11/3 - 2/3 - 6/3 ) x26/7
= 1 x 26/7
= 26 /7
Tick cho mình nha
a) 13 x 5 x 2 = 13 x (5 x 2)
= 13 x 10
= 130
5 x 2 x 34 = (5 x 2) x 34
= 10 x 34
= 340
b) 2 x 26 x 5 = (2 x 5) x 26
= 10 x 26
= 260
a) 13 x 5 x 2 5 x 2 x 34 b) 2 x 26 x 5
= 13 x ( 5 x 2 ) = ( 5 x 2 ) x 34 = ( 2 x 5 ) x 26
= 13 x 10 = 10 x 34 = 10 x 26
= 130 = 340 = 260
Chúc bạn học tốt!
26*8+2*2*13-10*26
=26*8+2*26-10*26
=26*(8+2-10)
=26*0
=0
Nhớ tick mik nha
