To apply the properties of integer exponents, we can use the following rules:
1. (a^m)^(n) = a^(m*n)
2. a^(-n) = 1/a^n
3. a^m/a^n = a^(m-n)
4. a^m * b^m = (a*b)^m
Now, let's simplify the expression step by step:
(7^(-3))^7 * 7^20 / 6^(-2)
Using rule 1: (7^(-3))^7 = 7^(-3*7) = 7^(-21)
So, the expression becomes: 7^(-21) * 7^20 / 6^(-2)
Using rule 3: 7^(-21) * 7^20 = 7^(-21+20) = 7^(-1)
So, the expression becomes: 7^(-1) / 6^(-2)
Using rule 2: 7^(-1) = 1/7^1 = 1/7
So, the expression becomes: 1/7 / 6^(-2)
Using rule 2 again: 6^(-2) = 1/6^2 = 1/36
So, the expression becomes: 1/7 / 1/36
Using rule 3: 1/7 / 1/36 = 1/7 * 36/1
Simplifying, the expression becomes: 36/7
Therefore, the answer is 36/7 as an improper fraction.

Let's reassess the expression and apply the properties of integer exponents correctly.
Given expression: (7^(-3))^7 * 7^20 / 6^(-2)
First, let's simplify (7^(-3))^7 using the property (a^m)^n = a^(m*n):
(7^(-3))^7 = 7^(-3*7) = 7^(-21)
Now, the expression becomes: 7^(-21) * 7^20 / 6^(-2)
Next, let's simplify 7^(-21) using the property a^(-n) = 1/a^n:
7^(-21) = 1/7^21
The expression now becomes: 1/7^21 * 7^20 / 6^(-2)
Using the property a/b * c/d = (a*c)/(b*d), let's combine the terms with the same bases:
(1/7^21 * 7^20) / 6^(-2) = (1/7^21 * 7^20) * 6^2
Now, let's simplify the expression using the property a^m * a^n = a^(m+n):
(1/7^21 * 7^20) * 6^2 = 1/7^1 * 6^2 = 6^2 / 7
Finally, we can solve for 6^2 / 7:
6^2 = 6*6 = 36
36 / 7 = 5 remainder 1
Therefore, the expression simplifies to 5 1/7 as an improper fraction.

Apologies for the confusion.
Let's simplify the expression correctly:
Given expression: (7^(-3))^7 * 7^20 / 6^(-2)
First, let's simplify (7^(-3))^7 using the property (a^m)^n = a^(m*n):
(7^(-3))^7 = 7^((-3) * 7) = 7^(-21)
Now, the expression becomes: 7^(-21) * 7^20 / 6^(-2)
Next, let's simplify 7^(-21) using the property a^(-n) = 1/a^n:
7^(-21) = 1/7^21
The expression now becomes: 1/7^21 * 7^20 / 6^(-2)
Using the property a/b * c/d = (a*c)/(b*d), let's combine the terms with the same bases:
(1/7^21 * 7^20) * 6^2 = 1/7^21 * 7^20 * 6^2
Now, let's simplify the expression using the property a^m * a^n = a^(m+n):
1/7^21 * 7^20 * 6^2 = 7^(20-21) * 6^2
7^(20-21) = 7^(-1), which is equivalent to 1/7.
Therefore, the expression simplifies to 1/7 * 6^2.
Simplifying further, 6^2 = 36.
Therefore, the expression simplifies to 1/7 * 36 = 36/7.
So, the answer is 36/7 as an improper fraction.
try using positive exponents
Apologies for the previous incorrect responses.
Let's simplify the expression using positive exponents:
Given expression: (7^(-3))^7 * 7^20 / 6^(-2)
Using the property (a^m)^n = a^(m*n), we can simplify (7^(-3))^7 to 7^(-3*7) = 7^(-21).
Now, the expression becomes: 7^(-21) * 7^20 / 6^(-2)
Using the property a^(-n) = 1/a^n, we can simplify 7^(-21) to 1/7^21.
The expression now becomes: 1/7^21 * 7^20 / 6^(-2)
Using the property a/b * c/d = (a*c)/(b*d), let's combine the terms with the same bases:
1/7^21 * 7^20 * 6^(-2) = 1 / (7^21 * 6^2)
Now, let's simplify 7^21 * 6^2:
7^21 = (7^3)^7 = 343^7
6^2 = 36
Therefore, the expression simplifies to: 1 / (343^7 * 36)
To solve the expression, we can write 343 as 7^3:
1 / (7^3)^7 * 36 = 1 / 7^(3*7) * 36 = 1 / 7^21 * 36
So, the answer is: 36 / 7^21 as an improper fraction.
To generate equivalent expressions with only positive exponents, we can use the properties of integer exponents. Let's break it down step-by-step:
Step 1: Simplify the exponents in (7^−3)^7
Recall that when you raise a power to another power, you multiply the exponents. So, in this case, the exponent of -3 is being raised to the power of 7. Multiplying the exponents gives us -3 * 7, which equals -21.
Therefore, (7^−3)^7 can be rewritten as 7^-21.
Step 2: Simplify the exponents in 7^20
Since we don't have any negative exponents here, we can leave it as it is.
Step 3: Simplify the exponents in 6^−2
Similar to step 1, we need to raise the exponent of -2 to its absolute value. In this case, |-2| equals 2. So, 6^-2 can be written as 6^2.
Now, let's rewrite the expression using the new exponents and then solve it.
(7^-3)^7 * 7^20 / 6^-2 can be rewritten as (1 / 7^21) * 7^20 / 6^2.
Now, using the property of division with exponents, subtract the exponents in the numerator and denominator:
(1 / 7^21) * 7^20 / 6^2 = 7^(20 - 21) / 6^2 = 7^-1 / 6^2.
Next, since we want positive exponents, we can rewrite 7^-1 as 1 / 7^1:
(1 / 7^1) / 6^2 = (1/7) / 6^2 = 1 / (7 * 6^2).
Now, we can simplify further:
1 / (7 * 6^2) = 1 / (7 * 36) = 1 / 252.
Therefore, the answer to the expression (7^-3)^7 * 7^20 / 6^-2, with positive exponents and expressed as an improper fraction, is 1/252.
