4x4x4x4=256

mình nhanh nhat tk nha

1 + 1 = 2

2 + 2 = 4

4 x 4 x 4 x 4 = 256

5 x 60 = 300

a ] mình thấy bạn hình như ghi sai đề

b ]    x : [ 25 + 417 ] = 138 = x : 442

x = 442 x 138 = 60996

24 x 36 + 18 x 24 + 18 x 45 - 18 x 7 = 18 x 24 x 2 + 18 x 24 + 18 x 45 - 18 x 7 =
18 x ( 48 + 24 + 45 - 7 ) = 18 x 110 = 1980

\(\frac{1}{3}+\frac{1}{9}+\frac{1}{27}+\frac{1}{81}=\frac{27+9+3+1}{81}=\frac{40}{81}\)

\(\frac{3}{5}< x< \frac{4}{5}\)  |  \(x=\frac{31}{50}\)

3,5 < x < 3,6 | x = 3,51

1 + 1 + 2 + 1 + 3 + 1 + 4 + 4 + 5 = 22

Mình nhanh nhất nhé !

1+1+2+1+3+1+4+4+5=22

1 + 1 +2 +1 +3+ 1 +4 + 4 + 5 = 22

\(5\times95+5\times4+5\)

\(=5\times\left(95+4+1\right)\)

\(=5\times100\)

\(=500\)

5 x 95 + 5 x 4 + 5

= 5 x ( 95 + 4 + 1 )

= 5 x 100

= 500

5 x 95 + 5 x 4 + 5

= 5 x ( 95 + 4 + 1 )

= 5 x 100

= 500

\(\frac{2}{5}+1=\frac{2+5}{5}=\frac{7}{5}\)

\(\frac{6}{7}.4=\frac{6.4}{7}=\frac{24}{7}\)

\(\frac{3}{7}:2=\frac{3}{7.2}=\frac{3}{14}\)

\(2:\frac{2}{4}=\frac{2.4}{2}=4\)

\(\frac{3}{4}.\frac{2}{9}+\frac{1}{3}=\frac{6}{36}+\frac{1}{3}=\frac{1}{6}+\frac{1}{3}=\frac{1}{2}\)

\(\frac{1}{4}:\frac{1}{3}-\frac{1}{2}=\frac{3}{4}-\frac{1}{2}=\frac{1}{4}\)

2/5 + 1  = 7/5

6/7 x 4 =24 /7

3/7 :2 =1/7

2:2/4 = 4

3/4 x 2/9 + 1/3  = 1/2

1/4 : 1/3 - 1/2 = 1/4

ai tk mk nhiều nhất và nhanh nhất mk sẽ tk cho 

48

6

7 tk nha

2 x 2 x 3 x 4 = 48

1 x 2 x 3 = 6

1 + 6 = 7

\(50000.\frac{1}{4}=12500\)

\(\text{Học tốt!!!}\)

12500 bạn nhé

12500

1 + 2 + 3 + 4 + 5 = 15

k mk nha

1 + 2 + 3 + 4 + 5 = 15

\(1+2+3+4+5\)

\(=3+3+4+5\)

\(=6+4+5\)

\(=10+5\)

\(=15\)
