bạn làm như bạn gia hân là đúng nhé

giải giúp mình bài 2 trên với ạ

Thế này à:

a, \(\frac{2^{13}+25}{2^{10}}\)

b, \(\frac{21^2.14.125}{35^5.6}\)

c,\(\frac{45^3.20^4.18^2}{180^5}\)

d, \(\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)

2 mũ 13 ta chia cho 2 mũ 10 ta có là 2 mũ 3 chuyển thành 8 rồi cộng cho 25 ta có là 33

mấy quân ni xoạc nên mới đâm ra thần kinh

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

mk cũng ko bt

??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

khó hiểu bạn ơi

Ta có : \(A=\frac{11.3^{22}.3^7-9^{15}}{\left(2.3^{14}\right)^2}\)

\(\Rightarrow\)  \(A=\frac{11.3^{22+7}-\left(3^2\right)^{15}}{2^2.\left(3^{14}\right)^2}\)

\(\Rightarrow\)  \(A=\frac{11.3^{29}-3^{30}}{2^2.3^{28}}\)

\(\Rightarrow\)  \(A=\frac{3^{29}.\left(11-3\right)}{2^2.3^{28}}\)

\(\Rightarrow\)  \(A=\frac{3^{29}.8}{2^2.3^{28}}\)

\(\Rightarrow\)  \(A=\frac{3^{29}.2^3}{2^2.3^{28}}\)

\(\Rightarrow\)  \(A=3.2\)

\(\Rightarrow\)  \(A=6\)

   Vậy A = 6
