Let's apply the Properties of Integer Exponents to generate equivalent expressions for the given expression.
(4^3 ⋅ 7^−2)−5^/7^9 ⋅ 4^−13
Using the property of multiplying powers with the same base, we can rewrite (4^3 ⋅ 7^−2) as 4^3 ⋅ 7^−2.
Using the property of dividing powers with the same base, we can rewrite 5^/7^9 as 5^7/7^9.
Therefore, the expression becomes:
(4^3 ⋅ 7^−2)/(5^7/7^9) ⋅ 4^−13
Now let's simplify the expression by applying the rules of exponents:
(4^3 ⋅ 7^−2)/(5^7/7^9) ⋅ 4^−13
Using the rule a^m/n = (n√a)^m:
(4^(3/1) ⋅ 7^(-2/1))/(5^(7/1) ⋅ 7^(9/1)) ⋅ 4^(-13/1)
Simplifying the exponents:
4^3 ⋅ 7^(-2)/(5^7 ⋅ 7^9) ⋅ 4^(-13)
Now, let's combine the like terms using the rule a^m ⋅ a^n = a^(m+n):
(4^3 ⋅ 7^(-2) ⋅ 4^(-13))/(5^7 ⋅ 7^9)
Applying the rule of subtracting exponents in the denominator:
(4^3 ⋅ 7^(-2) ⋅ 4^(-13))/(5^7 ⋅ 7^(9-7))
Simplifying the exponents:
(4^3 ⋅ 7^(-2) ⋅ 4^(-13))/(5^7 ⋅ 7^2)
Since we want to express everything with positive exponents, let's apply the rule a^(-n) = 1/(a^n):
(4^3 ⋅ 1/(7^2) ⋅ 1/(4^13))/(5^7 ⋅ 7^2)
Simplifying the expression:
(4^3)/(7^2 ⋅ 5^7 ⋅ 4^13)
Now, let's combine the powers using the rule a^m ⋅ b^m = (a⋅b)^m:
((4⋅4⋅4)/(7⋅7))/(5^7 ⋅ 4^13)
Simplifying further:
64/(49 ⋅ 4)/(5^7 ⋅ 4^13)
Now, let's express 4 as 2^2:
64/(49 ⋅ 2^2)/(5^7 ⋅ 2^13)
Simplifying:
64/(49 ⋅ 4)/(5^7 ⋅ 2^13)
Now, let's express 49 as 7^2:
64/(7^2 ⋅ 4)/(5^7 ⋅ 2^13)
Simplifying:
64/(7^2 ⋅ 4)/(5^7 ⋅ 2^13)
Now, let's simplify the expression inside the parentheses and combine like terms:
64/(49 ⋅ 4)/(2^13 ⋅ 5^7)
64/(196)/(8192 ⋅ 5^7)
Now, let's simplify further:
64/(196)/(8192 ⋅ 78125)
Now, let's divide 64 by 196:
1/(3)/(8192 ⋅ 78125)
Now, let's multiply 8192 and 78125:
1/(236,421,120)
So, the simplified fraction with no remaining exponents is 1/236,421,120.
