Answer:
k=3+6x
Step-by-step explanation:
the question says that k is an expression where x is a variable soo...
rewrite the given expressio with bases of 3
27×9^3x = 3k
3^3 × 3^2(3x) = 3k
Rule of exponent says that equal when you multiple you add exponent. Another rule says that equal bases cancel
3^6x+3 =3^k
6x+3=k
