What is the value of 3²/3^-1?
I figured out that 3² is 9 and that divided by 3^-1 was 30, but that was not one of the listed answers. Where did I go wrong and what is the correct answer?
Thank you! :-)
I believe three to the power of negative one is -3
so then 9/-3=-3
i'd say the answer is -3
The is how I would solve it
Since its division, you would subtract exopents
Since the numerator has a 2 as an exponent and the denominator has a -1 for an exponent I would subtract that
2-(-1) = 2 + 1
=3
3^3 = 27
If you have a negative exponent, just put a one on top of it to make it a positive.
Example:
3^-2 = 1/3^2
5^-3 = 1/5^3
7^-3 = 1/7^3
Please help me solve 2/3 x +1/6 x=2
Anita, please make your own post on that question and I will gladly help you.
To find the value of 3²/3^-1, let's first simplify the expression:
Step 1: Simplify the numerator (3²)
3² is equal to 3 * 3, which equals 9.
Step 2: Simplify the denominator (3^-1)
To simplify the denominator, remember that any number raised to the power of -1 is equivalent to its reciprocal. Therefore, 3^-1 is equal to 1/3.
Now, let's substitute the simplified numerator and denominator back into the expression:
9 / (1/3)
To divide by a fraction, we can multiply by its reciprocal. Therefore, the expression can be rewritten as:
9 * (3/1)
Multiplying 9 by 3/1, we get:
(9 * 3) / 1 = 27 / 1 = 27
So, the correct answer is 27.
It seems you made an error when simplifying 3^-1. Remember that any number raised to the power of -1 is its reciprocal. Thus, 3^-1 is equal to 1/3, not 30.
