Chịu, tự đi mà làm

3¹⁰ hay như nào em ơi?

b: \(\left(x-\dfrac{1}{3}\right)^3=-\dfrac{8}{27}\)

=>\(\left(x-\dfrac{1}{3}\right)^3=\left(-\dfrac{2}{3}\right)^3\)

=>\(x-\dfrac{1}{3}=-\dfrac{2}{3}\)

=>\(x=-\dfrac{2}{3}+\dfrac{1}{3}=-\dfrac{1}{3}\)

c: \(\left(5x+1\right)^2=\dfrac{36}{49}\)

=>\(\left[{}\begin{matrix}5x+1=\dfrac{6}{7}\\5x+1=-\dfrac{6}{7}\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}5x=\dfrac{6}{7}-1=-\dfrac{1}{7}\\5x=-\dfrac{6}{7}-1=-\dfrac{13}{7}\end{matrix}\right.\)

=>\(\left[{}\begin{matrix}x=-\dfrac{1}{7}:5=-\dfrac{1}{35}\\x=-\dfrac{13}{7}:5=-\dfrac{13}{35}\end{matrix}\right.\)

d: \(\left(\dfrac{1}{3}-\dfrac{3}{2}x\right)^2=2\dfrac{1}{4}\)

=>\(\left(\dfrac{3}{2}x-\dfrac{1}{3}\right)^2=\dfrac{9}{4}\)

=>\(\left[{}\begin{matrix}\dfrac{3}{2}x-\dfrac{1}{3}=\dfrac{3}{2}\\\dfrac{3}{2}x-\dfrac{1}{3}=-\dfrac{3}{2}\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}\dfrac{3}{2}x=\dfrac{3}{2}+\dfrac{1}{3}=\dfrac{11}{6}\\\dfrac{3}{2}x=-\dfrac{3}{2}+\dfrac{1}{3}=-\dfrac{7}{6}\end{matrix}\right.\)

=>\(\left[{}\begin{matrix}x=\dfrac{11}{6}:\dfrac{3}{2}=\dfrac{11}{6}\cdot\dfrac{2}{3}=\dfrac{11}{9}\\x=-\dfrac{7}{6}:\dfrac{3}{2}=-\dfrac{7}{6}\cdot\dfrac{2}{3}=-\dfrac{7}{9}\end{matrix}\right.\)

e: \(\left(\dfrac{4}{5}\right)^{2x+5}=\dfrac{256}{625}\)

=>\(\left(\dfrac{4}{5}\right)^{2x+5}=\left(\dfrac{4}{5}\right)^4\)

=>2x+5=4

=>2x=4-5=-1

=>\(x=-\dfrac{1}{2}\)

g: \(\left(\dfrac{1}{3}\right)^{x+1}+\left(\dfrac{1}{3}\right)^{x+2}=\dfrac{1}{12}\)

=>\(\left(\dfrac{1}{3}\right)^x\cdot\dfrac{1}{3}+\left(\dfrac{1}{3}\right)^x\cdot\dfrac{1}{9}=\dfrac{1}{12}\)

=>\(\left(\dfrac{1}{3}\right)^x\left(\dfrac{1}{3}+\dfrac{1}{9}\right)=\dfrac{1}{12}\)
=>\(\left(\dfrac{1}{3}\right)^x=\dfrac{1}{12}:\dfrac{4}{9}=\dfrac{1}{12}\cdot\dfrac{9}{4}=\dfrac{3}{4\cdot4}=\dfrac{3}{16}\)

=>\(x=log_{\dfrac{1}{3}}\left(\dfrac{3}{16}\right)\)

Mọi người giúp mk bài này với!

  A = \(\dfrac{3^2}{4}\) + \(\dfrac{3^2}{18}\) + \(\dfrac{3^2}{54}\) + \(\dfrac{3^2}{108}\) + \(\dfrac{3^2}{180}\) + \(\dfrac{3^2}{270}\)

A = \(\dfrac{9}{4}\) + \(\dfrac{1}{2}\) + \(\dfrac{1}{6}\) + \(\dfrac{1}{12}\) + \(\dfrac{1}{20}\) + \(\dfrac{1}{30}\)

A = \(\dfrac{9}{4}\)  + \(\dfrac{1}{1.2}\) + \(\dfrac{1}{2.3}\) + \(\dfrac{1}{3.4}\) + \(\dfrac{1}{4.5}\) + \(\dfrac{1}{5.6}\)

A = \(\dfrac{9}{4}\) + (\(\dfrac{1}{1}\) - \(\dfrac{1}{2}\) + \(\dfrac{1}{2}\) - \(\dfrac{1}{3}\) + \(\dfrac{1}{3}\) - \(\dfrac{1}{4}\) + \(\dfrac{1}{4}\) - \(\dfrac{1}{5}\) + \(\dfrac{1}{5}\) - \(\dfrac{1}{6}\))

A = \(\dfrac{9}{4}\) + \(\dfrac{1}{1}\) - \(\dfrac{1}{6}\)

A = \(\dfrac{54}{24}\) + \(\dfrac{24}{24}\) - \(\dfrac{4}{24}\)

A = \(\dfrac{78}{24}\) - \(\dfrac{4}{24}\)

A = \(\dfrac{37}{12}\)  

Em chọn vào biểu tượng \(\Sigma\) góc tái màn hình em nhé. Sau đó em nhấn biểu tượng phân số rồi em chèn phân số vào là được.

To stay healthy, you should eat a balanced diet with plenty of fruits and vegetables, exercise regularly, drink enough water, and get enough sleep. It's also important to maintain good hygiene and manage stress. You shouldn’t eat too much junk food, skip meals, or spend too much time being inactive. Avoid smoking, drinking alcohol, and overusing electronic devices to protect both your physical and mental health.
