By solving the expression, the value of c will be "[tex]81x^{28-n}[/tex]". A further explanation is below.
The given expression is:
- [tex](3x^7)^4 = cx^n[/tex]
By multiplying the powers in the bracket, we get
→ [tex]3^4x^{28} = cx^n[/tex]
By moving "[tex]x^n[/tex]" to the other side of the equation, we get
→ [tex]3^4x^{28} x^{-n} =c[/tex]
→ [tex]81x^{28-n} =c[/tex]
Thus the above answer is right.
