Question

if (7)^(-4) x (7)^12 = (7)^3y x (7)(-1), find the value of y.​

Answer 1

Answer:

solution, 7^(-4)×7^12=7^3y×7^-1

=7^-4+12=7^3y-1

=7^8=7^3y-1

=8=3y-1

=3y=-8-1

=3y=-9

=y=-9/3

y=-3

Answer 2

Answer:

y = 3

Step-by-step explanation:

(7)^(-4) x (7)^12 = (7)^3y x (7)^(-1)

7^-4+12 = 7^3y-1

-4+12 = 3y - 1

8 = 3y - 1

8+1 = 3y

9 = 3y

3y = 9

y = 9/3 = 3
