Expressing (-1/216) as Powers of Rational Numbers
Finding the Prime Factorization of the Denominator
To express the given rational number as powers of rational numbers, we need to find the prime factorization of the denominator, which is 216.
216 can be written as:
2 x 2 x 2 x 3 x 3 x 3
Expressing the Given Rational Number as Powers of Rational Numbers
Now that we have the prime factorization of the denominator, we can express the given rational number as powers of rational numbers.
-1/216 can be written as:
-1/(2 x 2 x 2 x 3 x 3 x 3)
Expressing -1 as a Power of -1
We can express -1 as a power of -1, which is -1^1.
-1/(2 x 2 x 2 x 3 x 3 x 3) = (-1)^1/(2 x 2 x 2 x 3 x 3 x 3)
Expressing 2 as a Power of 2
We can express 2 as a power of 2, which is 2^1.
(-1)^1/(2 x 2 x 2 x 3 x 3 x 3) = (-1)^1/2^3 x 3^3
Expressing 3 as a Power of 3
We can express 3 as a power of 3, which is 3^1.
(-1)^1/2^3 x 3^3 = (-1)^1/2^3 x 3^1 x 3^2
Final Answer
Therefore, (-1/216) can be expressed as:
(-1/216) = (-1)^1/2^3 x 3^1 x 3^2
or
(-1/216) = -1/8 x 27
