(6x5:X)+15=4
30:X=4-15=-11
=>X=30:(-11)=-\(\frac{30}{11}\)
hihi, chúc bn hk tốt nha >,<
=(30+7-37)x(1+2+3+4+5+6+7+8+9+10)
=(37-37)x(1+2+3+4+5+6+7+8+9+10)
=0x(1+2+3+4+5+6+7+8+9+10)
=0
126 x 56 + 94
= (12 x 5)6 + 94
= 606 + 94
= 46656000000 + 6561
=46656006561
a, 25 \(\times\)66 + 33 \(\times\) 25 + 25
= 25 \(\times\) 66 + 33 \(\times\) 25 + 25 \(\times\)1
= 25 \(\times\) ( 66 + 33 + 1)
= 25 \(\times\) ( 66 + 34)
= 25\(\times\) 100

\(\dfrac{2}{3}\) \(\times\) \(\dfrac{9}{7}\) + \(\dfrac{4}{6}\) \(\times\) \(\dfrac{5}{7}\) - \(\dfrac{2}{3}\)
= \(\dfrac{2}{3}\) \(\times\) \(\dfrac{9}{7}\) + \(\dfrac{2}{3}\) \(\times\) \(\dfrac{5}{7}\) - \(\dfrac{2}{3}\) \(\times\) 1
= \(\dfrac{2}{3}\) \(\times\) ( \(\dfrac{9}{7}\) + \(\dfrac{5}{7}\) - 1)
= \(\dfrac{2}{3}\) \(\times\) ( 2 - 1)
= \(\dfrac{2}{3}\) \(\times\) 1
= \(\dfrac{2}{3}\)
=(30+7-37)*(1+2+3+4+5+6+7+8+9+10)
