5 + 5 x 5 - 5 + 5 x 5 : 5 

= 5 + 25 - 5 + 5

= 30

= 5 + 25 - 5 + 25 : 5

= 5 + 25 - 5 + 5

= 30 - 5 + 5

= 25 + 5

= 30

150x150 = 22500

160x180x190x170x123=114419520000

500x1000x1234=617000000

500:5=100

707x101x555 =39630885

5x5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5=100

thanks

Số cần tìm là:

5 + 5 + 5 + 5 x 5 + 5 = 45.

5 + 5 + 5 + 5 * 5 + 5= 45

bằng 0

= 5 nhé bạn

5+5+5*5+5+5

=5+5+5+5+5+5+5+5+5

=5*9

=45

Nho h cho minh nhe

45 nha bn

kết bạn nha

\(\left(\dfrac{1}{5}\right)^5\cdot5^5+\dfrac{8^{13}}{4^{18}}\)

\(=1+\dfrac{2^{39}}{2^{36}}\)

=9

a) = 29/5

b) = 1/10

c) = 1/2

d) ?

a) \(\dfrac{12}{15}+5=\dfrac{4}{5}+5=\dfrac{4}{5}+\dfrac{25}{5}=\dfrac{29}{5}\)

b) \(\dfrac{7}{10}-\dfrac{6}{10}=\dfrac{1}{10}\)

c) \(\dfrac{3}{5}x\dfrac{5}{6}=\dfrac{15}{30}=\dfrac{1}{2}\)

d) lỗi 

a: =9/11(7/4+5/4)=9/11x3=27/11

b: \(=\dfrac{28}{5}\cdot\dfrac{5}{8}\cdot\dfrac{5}{4}=\dfrac{28}{8}\cdot\dfrac{5}{4}=\dfrac{140}{32}=\dfrac{35}{8}\)

c: \(=\dfrac{2}{6}+\dfrac{4}{5}\cdot\dfrac{6}{5}-\dfrac{2}{5}=\dfrac{67}{75}\)

a,=(7/4+5/4):11/9

=3:11/9

=27/11

b,=28/5.5/4.5/8

=7.5/8

=35/8

c,=1/3+24/25-2/5

=97/75-2/5

=67/75

bằng 20 nha bạn

5 + 5 - 5 x 5 : 5 = 5

k mik nhé
