Question

5^25.5^x-1=5^25

Answer 1

5²⁵.5^x-1=5²⁵

      5^x-1=5²⁵:5²⁵

      5^x-1= 5⁰

    =>x-1=0

         x=0+1

         x=1

vậy x=1

        

Answer 2

\(5^{25}.5^{x-1}=5^{25}\\ 5^{x-1}=5^{25}:5^{25}\\ 5^{x-1}=1\\ 5^{x-1}=5^0\\ x-1=0\\ x=0+1\\ x=1\)

Answer 4

5²⁵.5^x-1=5²⁵

      5^x-1=5²⁵:5²⁵

      5^x-1= 5⁰

    =>x-1=0

         x=0+1

         x=1
