To apply the properties of integer exponents and generate equivalent expressions with only positive exponents, we can use the following rules:
1. For any non-zero number x, x^(-n) = 1/x^n.
2. For any non-zero number x, x^0 = 1.
3. For any non-zero numbers a and b, a^n * b^n = (a * b)^n.
Using these rules, let's simplify the expression:
40 ⋅ 5^(-2)(-2)^(-3)
Using rule 1 for 5^(-2), we have:
40 ⋅ (1/5^2)(-2)^(-3)
Simplifying 5^2 = 25:
40 ⋅ (1/25)(-2)^(-3)
Using rule 2 for (-2)^(-3), we have:
40 ⋅ (1/25)(1/(-2)^3)
Simplifying (-2)^3 = -8:
40 ⋅ (1/25)(1/(-8))
Simplifying 1/(-8):
40 ⋅ (1/25)(-1/8)
Using rule 3 for (1/25)(-1/8), we have:
(40 * 1 * -1) / (25 * 8) = -40 / 200
Simplifying the fraction:
-40 / 200 = -1 / 5
Therefore, the solution is -1 / 5.
