bạn làm như bạn gia hân là đúng nhé

giải giúp mình bài 2 trên với ạ

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

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

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

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

\(=5^{13}\)

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

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

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

\(=104857600\)

\(125^3:25^4\)

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

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

\(=5\)

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

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

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

\(=0\)

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

a) \(4^{13}+4^{14}+4^{15}+4^{16}=4^{13}\left(1+4\right)+4^{14}\left(1+4\right)=4^{13}.5+4^{14}.5=5\left(4^{13}+4^{14}\right)⋮5\Rightarrow dpcm\)

c) \(2^{10}+2^{11}+2^{12}+2^{13}+2^{14}+2^{15}\)

\(=2^{10}\left(1+2+2^2\right)+2^{13}\left(1+2+2^2\right)\)

\(=2^{10}.7+2^{13}.7=7\left(2^{10}+2^{13}\right)⋮7\Rightarrow dpcm\)

Câu c bạn xem lại đê

Giải: (^ là mũ)

a) 3^8 : 3^4 + 2^2 . 2^3

= 6561 : 81 + 4 . 8

= 81 + 32

= 113

Mấy câu sau bn làm tương tự nhé!

b: \(=2^{12}\cdot3^4\cdot\dfrac{3^{10}}{3^{12}\cdot2^{12}}=3^2=9\)

c: \(=\dfrac{7^2\cdot3^2\cdot7\cdot2\cdot5^3}{5^3\cdot7^3\cdot2\cdot3}=\dfrac{3^2}{3}=3\)

d: \(=\dfrac{5^3\cdot3^6\cdot5^4\cdot2^8\cdot3^{16}\cdot2^2}{\left(2^2\cdot3^2\cdot5\right)^5}=\dfrac{5^{10}\cdot3^{22}\cdot2^{10}}{2^{10}\cdot3^{10}\cdot5^5}=3^{12}\cdot5^5\)
