Question

Tìm x biết

\(5^8\):\(25^2\)=\(\left(3^2-2^2\right)^x\)

Answer 1

\(\Leftrightarrow\)\(5^8:5^4=\left(9-4\right)^x\)

\(\Leftrightarrow5^4=5^x\)

\(\Leftrightarrow x=4\)

Answer 2

=> (9-4)^x=5⁸:(5²)²

=> 5^x=5⁸:5⁴

=> 5^x=5⁴

=> x=4

Answer 3

5⁸:25²=(3²-2²)^x

5⁸:5⁴=(9-4)^x

5⁴=5^x

suy ra x=4

Answer 4

 5^8 : 5^4 = ( 9 - 4 )^x

 5^4 = 5^x

=> x = 4
