If the product of two numbers is 1, then each number is known as multiplicative inverse or the reciprocal of one another. So,
3^4 * x = 1
==> x = 1 / 3^4 = 1 /81
Similarly for
7^-2 * y = 1
==> y = 1 / 7^-2 = 7^2 = 49
9^-9 * z = 1
==> z = 1 / 9^-9 = 9^9 = 387,420,489
10^-180 * a = 1
==> a = 1 / 10^-180 = 10^180
3^4 * x = 1
==> x = 1 / 3^4 = 1 /81
Similarly for
7^-2 * y = 1
==> y = 1 / 7^-2 = 7^2 = 49
9^-9 * z = 1
==> z = 1 / 9^-9 = 9^9 = 387,420,489
10^-180 * a = 1
==> a = 1 / 10^-180 = 10^180
