\(a=2^{100}=\left(2^4\right)^{25}=16^{25}\)
\(b=3^{75}=\left(3^3\right)^{25}=27^{25}\)
\(c=5^{50}=\left(5^2\right)^{25}=25^{25}\)
Vì: \(16^{25}< 25^{25}< 27^{25}\Rightarrow2^{100}< 5^{50}< 3^{75}\Rightarrow a< c< b\)
tíc mình nha
so sánh các số a,b,c
a=2100
b=375
c=550
\(=2^{100}=\left(2^{20}\right)^5\)
\(3^{75}=\left(3^{15}\right)^5\)
\(5^{50}=\left(5^{10}\right)^5\)
\(a=2^{100}=\left(2^4\right)^{25}=16^{25}\)
\(b=3^{75}=\left(3^3\right)^{25}=27^{25}\)
\(c=5^{50}=\left(5^2\right)^{25}=25^{25}\)
Vì: \(16^{25}< 25^{25}< 27^{25}\Rightarrow2^{100}< 5^{50}< 3^{75}\Rightarrow a< c< b\)
