a) \(\dfrac{13}{15}< \dfrac{14}{15}\) ( vì 13 < 14 )
b) Ta có:
\(\dfrac{2}{3}=\dfrac{2\times3}{3\times3}=\dfrac{6}{9}\)
Vì 6 = 6 nên \(\dfrac{6}{9}=\dfrac{6}{9}\)
Vậy \(\dfrac{2}{3}=\dfrac{6}{9}\)
c) Ta có:
\(\dfrac{4}{7}=\dfrac{4\times6}{7\times6}=\dfrac{24}{42}\)
\(\dfrac{5}{6}=\dfrac{5\times7}{6\times7}=\dfrac{35}{42}\)
Vì 24 < 35 nên \(\dfrac{24}{42}< \dfrac{35}{42}\)
Vậy \(\dfrac{4}{7}< \dfrac{5}{6}\)
d) Vì 9 < 13 nên \(\dfrac{4}{9}>\dfrac{4}{13}\)
Vậy \(\dfrac{4}{9}>\dfrac{4}{13}\)

2 Because Lan was sick, she was absent from class yesterday
3 How heavy is the parcel?

6:
\(2^{225}=\left(2^3\right)^{75}=8^{75}\)
\(3^{150}=\left(3^2\right)^{75}=9^{75}\)
mà 8<9
nên \(2^{225}< 3^{150}\)
4: \(\left|5x+3\right|>=0\forall x\)
=>\(-\left|5x+3\right|< =0\forall x\)
=>\(-\left|5x+3\right|+5< =5\forall x\)
Dấu = xảy ra khi 5x+3=0
=>x=-3/5
1:
\(\left(2x+1\right)^4>=0\)
=>\(\left(2x+1\right)^4+2>=2\)
=>\(M=\dfrac{3}{\left(2x+1\right)^4+2}< =\dfrac{3}{2}\)
Dấu = xảy ra khi 2x+1=0
=>x=-1/2
