Chúc bạn học tốt!! ^^
a) \(2^2=4\)
\(2^3=8\)
\(2^4=16\)
\(2^5=32\)
\(2^6=64\)
b) \(3^2=3\)
\(3^3=27\)
\(3^4=81\)
\(3^5=243\)
c) \(4^2=16\)
\(4^3=64\)
\(4^4=256\)
d) \(5^2=25\)
\(5^3=125\)
a: \(\left(3^2\right)^3=3^6\)
\(\left(3^3\right)^2=3^6\)
\(\left(3^2\right)^5=3^{10}\)
\(9^8=3^{16}\)
\(27^6=3^{18}\)
\(81^{10}=3^{40}\)
b: \(\left(5^3\right)^2=5^6\)
\(\left(5^2\right)^4=5^8\)
\(\left(5^4\right)^3=5^{12}\)
\(25^5=5^{10}\)
\(125^{14}=5^{42}\)
a) Cách 1: \(\left(3^2\right)^3=3^{2.3}=3^6\)
\(\left(3^3\right)^2=3^{3.2}=3^6\)
\(\left(3^2\right)^5=3^{2.5}=3^{10}\)
\(9^8=\left(3^2\right)^8=3^{2.8}=3^{16}\)
\(27^6=\left(3^3\right)^6=3^{3.6}=3^{18}\)
\(81^{10}=\left(3^4\right)^{10}=3^{4.10}=3^{40}\)
Cách 2: \(\left(3^2\right)^3=9^3\)
\(\left(3^3\right)^2=3^{3.2}=\left(3^2\right)^3=9^3\)
\(\left(3^2\right)^5=9^5\)
\(9^8\)
\(27^6=\left(3^3\right)^6=3^{3.6}=3^{18}=3^{2.9}=\left(3^2\right)^9=9^9\)
\(81^{10}=\left(9^2\right)^{10}=9^{2.10}=9^{20}\)
Trả lời :
b)
Ta có : \(5^{28}=5^{2.14}=\left(5^2\right)^{14}=25^{14}< 26^{14}\)
\(\Rightarrow5^{28}< 26^{14}\)
\(a,23\cdot24\cdot2=2^4\cdot3\cdot23\)
\(b,52\cdot57\cdot53=2^3\cdot3\cdot13\cdot19\cdot53\)
\(c,30\cdot35\cdot37=2\cdot3\cdot5^2\cdot7\cdot37\)
