Question

tìm x biết:\(^{5^x+5^{x+2}=650}\)

Answer 1

5^x + 5^x+2 = 650

=> 5^x . (1 + 5²) = 650

=> 5^x . 26 = 650

=> 5^x = 25 = 5²

=> x = 2

Answer 2

5^X(1+25)=650

5^Xx26=650

5^x=25

x=5

Answer 3

\(5^x+5^{x+2}=650\)

\(=>5^x\left(1+5^2\right)=650\)

\(=>5^x.26=650\)

\(=>5^x=5^2\)

\(=>x=2\)

Answer 4

\(5^x+5^{x+2}=650\)

=> \(5^x.\left(1+5^2\right)=650\)

=>\(5^x.26=650\)

\(5^x=25\)

VÌ \(5^x=5^2\Rightarrow x=2\)
