Cho P = 20223 và Q = 2021.2022.2023
Không tính cụ thể các giá trị của P và Q, hãy so sánh P và Q
3/5+5/7*3/5-9/7*3/5
help me help me
\(\dfrac{3}{5}+\dfrac{5}{7}\) x \(\dfrac{3}{5}-\dfrac{9}{7}\) x \(\dfrac{3}{5}\)
\(=\dfrac{3}{5}+\left(\dfrac{5}{7}-\dfrac{9}{7}\right)\) x \(\dfrac{3}{5}\)
\(=\dfrac{3}{5}-\dfrac{4}{7}\) x \(\dfrac{3}{5}\)
\(=\dfrac{3}{5}-\dfrac{12}{35}\)
\(=\dfrac{21}{35}-\dfrac{12}{35}=\dfrac{21-12}{35}=\dfrac{9}{35}\)

a, x+3 /8= 2/x-3 help help me
\(\frac{x+3}{8}=\frac{2}{x-3}\)
\(\left(x+3\right)\times\left(x-3\right)=2\times8\)
\(x^2-3^2=16\)
\(x^2-9=16\)
\(x^2=16+9\)
\(x^2=25\)
\(x^2=\left(\pm5\right)^2\)
\(x=\pm5\)
Vậy x = 5 hoặc x = -5

\(\frac{x+3}{8}=\frac{2}{x-3}\)
\(\Rightarrow\left(x+3\right)\left(x-3\right)=2.8=16\)
\(\Rightarrow x^2-3^2=16\)
\(\Rightarrow x^2=16+3^2=25\)
\(\Leftrightarrow\left[\begin{array}{nghiempt}x=5\\x=-5\end{array}\right.\)
