viet cach lam luon nha
Ta có:\(2^{36}\)và \(3^{27}\)
\(2^{36}=\left(2^4\right)^9=16^9\)
\(3^{27}=\left(3^3\right)^9=27^9\)
Vì \(16< 27\Rightarrow16^9< 27^9\)
Vậy....
b,\(9^{20}\)và \(9999^{10}\)
\(9^{20}=\left(9^2\right)^{10}=81^{10}\)
\(9999^{10}\)
Vì \(81< 9999\Rightarrow81^{10}< 9999^{10}\)
Vậy ...
c,\(54^4\)
\(21^{12}=\left(21^3\right)^4=9261^4\)
Vì \(54< 9261\Rightarrow54^4< 9261^4\)
Vậy...
So sanh
a ] 10 mu 20 va 19 mu 10
b ] [ -5 ] mu 30 va [ -3 ] mu 50
c ] 64 mu 8 va 16 mu 12
So sanh 4 mu 30 va 8 mu 12
1) Viet cac so 2 mu 27 va 3 mu 18 duoi dang luy thua co so mu la9
So sanh (2mu31)mu100 va (3mu21)mu 100
cho A= 2x mu 2-10xy+2016y mu 2+y va B=5x mu 2-7xy+2016y mu 2+7y-2016.tim C biet A+C=B
tim cac tu nhien a va b sao cho 2 mu a + 2 mu b = 2 mu a+b
tim cac tu nhien a va b sao cho 2 mu a + 2 mu b = 2 mu a+b
so sánh 3^21 va 2^31
32^9 va 18^3
^ là mu
so sánh 3^21 va 2^31
32^9 va 18^3
^ là mu
