Answer:

  • product of powers
  • power of a power
  • negative exponent

Explanation:

The value in square brackets is evaluated using the product of powers rule:

(7^5)(7^3) = 7^(5+3) = 7^8

Then the overall value is found using the power of a power rule:

[7^8]^-4 = 7^(8(-4)) = 7^-32

Finally, the expression value is found using the negative exponent rule:

7^(-32) = 1/7^32 = 1/1104427674243920646305299201
