If the power 7^15 was simplified using the Power Rule of Exponents, which of the following would be an expanded equivalent expression?
A. (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7)
B. (7^18)^3
C. (7 * 7 * 7 * 7 * 7)^10
D. (7^10)^5
To simplify the expression 7^15 using the power rule of exponents, we need to remember that the rule states that when we raise a number to a power and then raise that result to another power, we need to multiply the exponents.
In this case, 7^15 can be thought of as (7^3)^5, since 15 is divisible by 3.
Now let's look at each of the answer choices to determine which one matches the given expression:
A. (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7)
This expression represents 5 sets of 7^3 multiplied together. It is equivalent to (7^3)^5, which matches our simplified expression.
B. (7^18)^3
This expression represents 7^18 raised to the power of 3, which is not equivalent to 7^15.
C. (7 * 7 * 7 * 7 * 7)^10
This expression represents 5 sets of 7 multiplied together, then raised to the power of 10. It is not equivalent to 7^15.
D. (7^10)^5
This expression represents 7^10 raised to the power of 5, which is not equivalent to 7^15.
Therefore, the expanded equivalent expression for 7^15, obtained by simplifying using the power rule of exponents, is A. (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7).
The Power Rule of Exponents states that when you have a power raised to another power, you multiply the exponents. In this case, the power of 7^15 can be simplified by multiplying the exponents.
So, the expanded equivalent expression would be:
A. (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7) * (7 * 7 * 7)
This is not equivalent to 7^15.
B. (7^18)^3
This is not equivalent to 7^15.
C. (7 * 7 * 7 * 7 * 7)^10
This is not equivalent to 7^15.
D. (7^10)^5
This is not equivalent to 7^15.
Therefore, none of the options provided is the expanded equivalent expression of 7^15 using the Power Rule of Exponents.
To simplify the expression 7^15 using the Power Rule of Exponents, we can expand the base 7 using multiplication.
The Power Rule of Exponents states that when you have a base raised to an exponent, and that is raised to another exponent, you can multiply the exponents together.
So, we have:
7^15 = (7^3)^5
Expanding the base 7^3, we get:
(7^3)^5 = (7 * 7 * 7)^5
This means that the expanded equivalent expression is:
C. (7 * 7 * 7 * 7 * 7)^10
What do you mean A is correct for me?
Apologies for the confusion. The correct answer for the expanded equivalent expression of 7^15 using the power rule of exponents is not A.
The correct answer is C. (7 * 7 * 7 * 7 * 7)^10.
Once again, I apologize for the error in my previous response. Thank you for bringing it to my attention.
