Question

tính :

M = \(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)

các bạn giúp mk giải kĩ vào nhé

Answer 1

 \(M=\frac{\left(2^3\right)^{20}+\left(2^2\right)^{20}}{\left(2^2\right)+\left(2^6\right)^5}\)

\(M=\frac{2^{60}+2^{40}}{2^{50}+2^{30}}\)

\(M=\frac{2^{40}\cdot2^{20}+2^{40}\cdot1}{2^{30}\cdot2^{20}+2^{30}\cdot1}\)

\(M=\frac{2^{40}\cdot\left(2^{20}+1\right)}{2^{30}\cdot\left(2^{20}+1\right)}\)

\(M=\frac{2^{40}}{2^{30}}\)

\(M=2^{40-30}\)

\(M=2^{10}\)

\(M=1024\)

Answer 2

M=8²⁰ +4²⁰/4²⁵+64⁵

M=(2³)²⁰+(2²)²⁰/(2²)²⁵+(2⁵)⁵

M=2⁶⁰+2⁴⁰/2⁵⁰+2²⁵

M=2²⁵(2³⁵+2¹⁵)/2²⁵(2²⁵+1)

M=2³⁵+2¹⁵/2²⁵+1

Answer 3

\(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)=\(\frac{\left(2^3\right)^{20}+\left(2^2\right)^{20}}{\left(2^2\right)^{25}+\left(2^6\right)^5}\)=\(\frac{2^{60}+2^{40}}{2^{50}+2^{30}}\)=\(\frac{2^{100}}{2^{80}}\)=2²⁰

Answer 4

hình như mik làm sai 

Answer 5

sai rồi còn nói

Answer 6

1024 nha bạn 

Answer 7

\(M=\frac{8^{20}+4^{20}}{4^{25}+64^5}\)

\(\Rightarrow M=\frac{\left(2^3\right)^{20}+\left(2^2\right)^{20}}{\left(2^2\right)^{25}+\left(2^6\right)^5}\)

\(\Rightarrow M=\frac{2^{60}+2^{40}}{2^{50}+2^{30}}\)

\(\Rightarrow M=\frac{2^{40}.2^{20}+2^{40}}{2^{30}.2^{20}+2^{30}}\)

\(\Rightarrow M=\frac{2^{40}.\left(2^{20}+1\right)}{2^{30}.\left(2^{20}+1\right)}\)

\(\Rightarrow M=\frac{2^{40}}{2^{30}}\)

\(\Rightarrow M=2^{10}\)

\(\Rightarrow M=1024\)
