Question

9×3^x+2=729
find the value of x​

Answer 1

(9x3)^x+2=729
So,
27^x+2=27^2
So,
Powers here are
X+2=2
X=2-2
X=0
Hope this helps.

Answer 2

9×3^x+2=729

=>(3²)×(3^x+2)=(3^6)

=>[3^(2+x+2)]=(3^6). [a^m×a^n=a^m+n]

=>[3^(x+4)]=3^6

bases are equal so, we should equal the powers

=>x+4=6

=>x=6-4

=>x=2
