2003^{2^0^1^0} = 2003^{2^0^1} = 2003^{2^0} = 2003¹ = 2003

NHỚ TIK f.t THEO DÕI NHA

\(\frac{9^9\cdot225^5\cdot8^7}{18^{12}\cdot625^3\cdot24^3}=\frac{9^9\cdot\left(\left(3\cdot5\right)^2\right)^5\cdot8^7}{\left(9\cdot2\right)^{12}\cdot\left(\left(5^2\right)^2\right)^3\cdot\left(8\cdot3\right)^3}\)

\(=\frac{1}{9^3\cdot2^{12}}\cdot\frac{9^5\cdot5^{10}}{5^{12}}\cdot\frac{8^7}{8^3\cdot3^3}\)

\(=\frac{9^2\cdot8^4}{2^{12}\cdot5^2\cdot3^3}\)

\(=\frac{9\cdot\left(2^4\right)^3}{\left(2^4\right)^3\cdot5^2}\)

\(=\frac{9}{25}\)

\(\frac{15}{25}=\frac{15:5}{25:5}=\frac{3}{5}\); \(\frac{6}{21}=\frac{6:3}{21:3}=\frac{2}{7}\)

\(\frac{3}{5}+\frac{2}{7}=\frac{31}{35}\)

\(\frac{15}{25}+\frac{6}{21}=\frac{3}{5}+\frac{2}{7}=\frac{21}{35}+\frac{10}{35}=\frac{31}{35}\)

15/25+6/21

ta có:

15/25=15:5/25:5=3/5

6/21=6:3/21:3=2/7

3/5+2/7=31/35

tick nha

hỏi chơi à?

4/5*5/24*1 và 1/7

miru

Rút gọn rồi tính: 

\(\frac{28}{35}.\frac{15}{72}.1\frac{7}{49}\)

\(=\frac{4}{5}.\frac{5}{24}.\frac{56}{49}\)

\(=\frac{4.5.8}{5.24.7}=\frac{4}{21}\)

\(\frac{28}{35}.\frac{15}{72}.1\frac{7}{49}\)

\(=\frac{4}{5}.\frac{5}{24}.\frac{7}{49}\)

\(=\frac{4}{21}\)

k mk nha, cảm ơn những người đã k

\(a,\frac{1}{8}+\frac{5}{8}=\frac{1+5}{8}=\frac{6}{8}=\frac{6:2}{8:2}=\frac{3}{4}\)

\(b,\frac{5}{9}+\frac{7}{9}=\frac{5+7}{9}=\frac{12}{9}=\frac{12:3}{9:3}=\frac{4}{3}\)

A)2/7:4/5=2/7*5/4=10/28=5/14

b)3/8:9/4=3/8*4/9=12/72=1/6

c)8/21:4/7=8/21*7/4=56/84=2/3

D)5/8:15/8=5/8*8/15=40/120=1/3

k nha
