Respuesta :

The value x at which the equation 3 Superscript 4 x Baseline = 27 Superscript x minus 3 satisfy is, -9.

What is an unknown variable?

Unknown variables are used to find the unknown values of the problem using the algebraic expressions.

The equation for the unknown variable x is given as,

[tex]3^{4x}=27^{x-3}[/tex]

The number 27 can be written as 3³. Thus,

[tex]3^{4x}=3^{3(x-3)}[/tex]

When, the base of  both side of the equation is same, then the exponent can be compared directly. Thus,

[tex]4x=3(x-3)[/tex]

Solve it further,

[tex]4x=3(x-3)\\4x=3x-9\\4x-3x=-9\\x=-9[/tex]

Thus, the value x at which the equation 3 Superscript 4 x Baseline = 27 Superscript x minus 3 satisfy is, -9.
