Question

9 . 5^{x - 3} = 6 . 5⁶ + 3 . 5⁶

^{Giups mk cn này nhé, giải ra hộ mk luôn nha, cảm ơn} 

Answer 1

9.5^x-3=5^6.(6+3)

9.5^x-3=5^6.9

=>5^x-3=5^6

=>x-3=6

=>x=9

Vậy x=9

Answer 2

 \(9.5^{x-3}=6.5^6+3.5^6\)

=>  \(9.5^{x-3}=\left(6+3\right).5^6\)

=>  \(9.5^{x-3}=9.5^6\)

=>  \(5^{x-3}=5^6\)

=>  x - 3 = 6

=>  x = 9

Answer 3

9.5^x-3=6.5⁶+3.5⁶

9.5^x-3=5⁶(6+3)

9.5^x-3=5⁶.9

5^x-3=5⁶(9:9)

5^x-3=5⁶

X-3=6

x=6-3

x=3

Answer 4

9 . 5^{x - 3} = 6 . 5⁶ + 3 . 5⁶

9 . 5^{x - 3} = ( 6 + 3 ) . 5⁶

9 . 5^{x - 3} = 9 . 5⁶

=> 5^{x - 3} = 5⁶

=> x = 6 - 3

=> x = 3

Answer 5

x = 9
