\(\left(22+88\right)\)\(\times\)\(\left(136+64\right)\)
\(=110.200\)
\(=22000\)
tk cho mk nha mk nhanh nhất!!!
22. 64+ 88. 136
= 22. 64+ 22. 4. 136
= 22. 64+ 22. 544
= 22( 64+ 544)
= 22. 608
= 11376.

Đây là dãy số cách đều 3 đơn vị
Số số hạng là:
( 44 - 2 ) : 3 + 1 = 15 ( số )
Tổng là:
( 44 + 2 ) x 15 : 2 = 345

cô ơi cho con hỏi
11 mũ 5 chia cho 11 mũ n trừ 4 bằng 11 mũ 5
giúp tính bài giải cho con nhé

231+(312-x)=531
<=> 312 - x = 531 - 231
<=> 312 - x = 300
<=> - x = 300 - 312
<=> - x = - 12
<=> x = 12

<=> 46-x+11=-48
<=> x= 46+11+48
<=>x= 105
Vậy x=105
Chúc bạn học tốt nha!

a. 22 x (64+35+1)
= 22 x 100
=2200
b. \(577-[5.\left(509-9\right)-2223]\)
= \(577-\left(5.500-2223\right)\)
=\(577-22777\)
=-22200

\(a.\frac{8}{7}+\frac{4}{7}\times\left(-\frac{6}{11}\right)-\frac{4}{7}\times\frac{5}{11}\)
\(=\frac{8}{7}+\frac{4}{7}\left(-\frac{6}{11}-\frac{5}{11}\right)\)
\(=\frac{8}{7}+\frac{4}{7}.\left(-1\right)\)
\(=\frac{8}{7}-\frac{4}{7}\)
\(=\frac{4}{7}\)
