How do I evaluate (1/9)^3
1 answer:
Answer:
Step-by-step explanation:
First recognize that 1/9 is equal to 3^-2
This is because when we add a negative exponent to a number we start to express its exponents as a fraction of 1.
Let me further explain
6^1 = 6
6^2 = 36
So... using this logic
6^-1 = 1/6
6^-2 = 1/36
So for this problem..
1/9 = 3^-2
Then we have a power to a power which when you have a power raised to a power, you multiply
So.. (3^-2)^3 = 3 which is the base to the power of -2 x 3 which is -6
So the answer is 3^-6
Which equals 1/3^6 power which is 1/729.

Step 4 is where she made the error.
Step-by-step explanation:
This step is actually known as the commutative property. That property states that we can change the order of numbers as long as we keep the signs and it maintains it's validity.
