bạn làm như bạn gia hân là đúng nhé

giải giúp mình bài 2 trên với ạ

Bằng 365:365=1

Là vậy đó bạn

a) \(9^{21}.9^{33}=9^{21+33}=9^{54}\)

b) \(19^{11}.19.19=19^{11+1+1}=19^{13}\)

c) \(25^2.5^2.125=5^4.5^2.5^3=5^{4+2+3}=5^9\)

d) \(t^{2021}.t^2.\left(t^2\right)^2=t^{2021}.t^2.t^4=t^{2021+2+4}=t^{2027}\)

e) \(123^{14}:123^{13}=123^{14-13}=123\)

f) \(64^2:8^3=\left(8^2\right)^2:8^3=8^4:8^3=8^{4-3}=8=2^3\)

g) \(6^{10}:6^3:36=6^{10}:6^3:6^2=6^{10-3-2}=6^5\)

h) \(m^{20}:m^{10}.m^{10}=m^{20-10+10}=m^{20}\)

a)\(\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{20}.3^{12}}=\frac{-5}{9}\)

b)\(\frac{\left(-11\right)^5.13^7}{11^5.13^8}=-\frac{1}{13}\)

c)\(\frac{2^{10}.3^{10}-2^{10}.3^9}{2^9.3^{10}}=\frac{2^{10}.3^9\left(3-1\right)}{2^9.3^{10}}=2\)

d(\(\frac{5^{11}.7^{12}+5^{11}.7^{11}}{5^{12}.7^{12}+9.5^{11}.7^{11}}=\frac{5^{11}.7^{11}\left(7+1\right)}{5^{11}.7^{11}\left(35+9\right)}=\frac{1}{6}\)

giúp mk vs nha

mấy bạn tính nhanh cho mình câu này với

        5 mũ 5 : 5 mũ 3 - 5

3. 3³.19-3³.12=3³.(19-12)=3³.7=189

4. 3.5²-16:2²=3.5²-2⁴:2²=3.25-4=75-4=71

Tính :  10 mũ 2 = 100 ; 11 mũ 2 = .121 ; 12 mũ 2 = 144 ;  13 mũ 2 =169; 14 mũ 2 =196 ;  15 mũ 2 = 225 ;  16 mũ 2 = 256 ; 17 mũ 2 =289  ; 18 mũ 2  =324  ; 19 mũ 2 = 361 ; 20 mũ 2 = 400 

\(5^{12}.7-5^{11}.10\)

\(=5^{11}.\left(5.7-10\right)\)

\(=5^{11}.25\)

\(=5^{11}.5^2\)

\(=5^{13}\)

\(2^{20}.15+2^{20}.85\)

\(=2^{20}.5\left(3+17\right)\)

\(=2^{20}.100\)

\(=104857600\)

\(125^3:25^4\)

\(=\left(5^3\right)^3:\left(5^2\right)^4\)

\(=5^9:5^8\)

\(=5\)

\(24^4:3^4-32^{12}:16^{12}\)

\(=\left(24:3\right)^4-\left(32:16\right)^{12}\)

\(=8^4-2^{12}\)

\(=0\)
