Question

Tìm x:            5^(x-2).(x+3)=1

Answer 1

5^(x-2)(x+3)=1=5^0

=>(x-2)(x+3)=0

<=>x-2=0 or x+3=0

<=>x=2 or x=-3

Vậy:..

Answer 2

5^(x-2)(x+3)=1

=>(x-2)(x+3)=0

=>x-2=0 hoặc x+3=0

=>x=2;-3

vậy x=-3;2

Answer 3

5^(x-2).(x+3)=1=5⁰

=>(x-2).(x+3)=0

=>x-2=0=>x=2

hoặc x+3=>x=-3

Vậy x=2,-3
