Question

Apply the product rule of integer exponents to find the numerical equivalent of 12 ^ - 5 * 12 ^ 7

Answer 1

To apply the product rule of integer exponents, we add the exponents when multiplying two numbers with the same base.

So, to find the numerical equivalent of 12^-5 * 12^7, we can combine the exponents:

12^-5 * 12^7 = 12^(-5 + 7)

= 12^2

= 144

Therefore, the numerical equivalent of 12^-5 * 12^7 is 144.
