Question

Find the value of the following step by step

3^12+n*9^2n-7
-------------------------
3^5n

Answer 1

Answer:3^5n-2

Step-by-step explanation:

3^12+n * 9^2n-7

=> 3^12+n * (3^2)^2n-7

=>3^12+n * 3^4n-14

=> 3^(12+n+4n-14)        When bases same, powers are added

=>3^5n-2

Answer 2

Answer:

3^

Step-by-step explanation:

3^12+n x 3^(2)(4n-14) /3^5n

3^(12+n)+(4n-14) - 5n....... using exponent property

3^-2

ans 1/3^2

1/9
