Apply the Properties of Integer Exponents to generate equivalent expressions to (7^−3)7 ⋅ 7^20/6^−2 with only positive exponents, then solve the expression. Provide the answer as an improper fraction
To apply the properties of integer exponents and generate equivalent expressions with only positive exponents, we can use the following rules:
1. Product of Powers Property: a^m * a^n = a^(m + n)
2. Quotient of Powers Property: a^m / a^n = a^(m - n)
3. Power of a Power Property: (a^m)^n = a^(m * n)
4. Negative Exponent Property: a^(-m) = 1 / a^m
Now let's go step by step:
(7^(-3)) * 7 * 7^(20) / (6^(-2))
First, let's simplify the negative exponents using the Negative Exponent Property:
(1 / 7^3) * 7 * 7^(20) / (1 / 6^2)
Now let's simplify the products and quotients using the Product of Powers Property and Quotient of Powers Property:
(1 / 7^3) * 7 * 6^2 * 7^(20)
Since 7^3 is the same as 1 / 7^(-3), we can rewrite it as:
7^(-3) * 7 * 6^2 * 7^(20)
Now let's apply the Power of a Power Property to 7^(20):
7^(-3) * 7 * 6^2 * (7^2)^10
Simplifying further:
7^(-3) * 7 * 6^2 * 7^20
Now, let's apply the Product of Powers Property again:
7^(-3 + 1) * 6^2 * 7^20
Simplifying the exponents:
7^(-2) * 6^2 * 7^20
Now, let's combine the expressions:
(6^2 * 7^20) / 7^2
Using the Quotient of Powers Property:
6^2 * 7^(20 - 2)
Simplifying:
6^2 * 7^18
Now, let's compute this expression:
6^2 = 6 * 6 = 36
7^18 is a large number that cannot be easily calculated, so we will leave it as is.
Therefore, the final expression in the form of an improper fraction is:
36 * 7^18
Please note that if you need an actual numerical answer, you would need to use a calculator or a computer program to compute 7^18, as it is a very large number.
That's not an improper fraction is it
You're correct, I apologize for the confusion. The expression we obtained, 36 * 7^18, is not in the form of an improper fraction. An improper fraction is a fraction where the numerator is greater than or equal to the denominator. To convert the expression into an improper fraction, we can rewrite it as:
36 * 7^18 / 1
This means the denominator is equal to 1, which is the same as multiplying the numerator by 1. Therefore, the expression can be written as the improper fraction:
(36 * 7^18) / 1
So the answer, written as an improper fraction, is:
(36 * 7^18) / 1
Is this correct?
I apologize for the confusion in my previous responses. You are correct, the expression in the form of an improper fraction should be simplified further.
Starting from the expression:
(6^2 * 7^18) / 7^2
We know that 7^18 / 7^2 is equal to 7^(18-2), so we can simplify the expression as:
(6^2 * 7^(18-2))
Which simplifies to:
(6^2 * 7^16)
Now, let's compute this expression:
6^2 = 6 * 6 = 36
Therefore, the final expression in the form of an improper fraction is:
36 * 7^16
I apologize for any confusion caused earlier, and appreciate your patience.
