Question

So sánh 2 số A=(2^5)^8 . 4^10 và B= 2^0 .4^10 .8^12.16

Answer 1

\(\left(2^5\right)^8\times4^{10}=2^{40}\times\left(2^2\right)^{10}=2^{40}\times2^{20}=2^{60}\)

\(2^0\times4^{10}\times8^{12}\times16=1\times\left(2^2\right)^{10}\times\left(2^3\right)^{12}\times2^4=2^{20}\times2^{36}\times2^4=2^{60}\)

\(\Rightarrow A=B\)

Answer 2

A=(2⁵)⁸*4¹⁰

=2⁴⁰*(2²)¹⁰

=2⁴⁰*2²⁰

=2⁶⁰

B=2⁰*4¹⁰*8¹²*16

=1*(2²)¹⁰*(2³)¹²*2⁴

=2²⁰*2³⁶*2⁴

=2⁶⁰

Vì 2⁶⁰=2⁶⁰ =>A=B
