_______________________________________________
Note:
_______________________________________________
The question asks:
_______________________________________________
If (5⁴)ᵐ = 5¹² ; then what is "m" ?

Note the following property of exponents:
________________________________________________
(xᵃ)ᵇ = x⁽ᵃ*ᵇ⁾ ; a≠0 ; b ≠ 0 ;

Then, (5⁴)³ = 5⁽⁴ * ³⁾ = 5¹² .

So, "12 ÷ 4 = 3" .
