The next number is 243, because 81x3=243.
243 = 3 x 3 x 3 x 3 x 3 = 35
it's only divisible by 3 243 divided by 3 is 81
1, 3, 9, 27, 81 and 243.
The base and exponent form a pair. You can chose any positive base and that will determine the exponent.243 = 49^1.5 that is base = 49, exponent = 1.5)or 243 = 10^2.5353 (approx) or 243 = 7^3.
3 3^5 = 243 (3 x 3) x (3 x 3) x 3 = 243 9 x 9 x 3 = 243 81 x 3 = 243
The prime factors of 243 are 3 * 3 * 3 * 3 * 3 So 243 = 3^5
It is: 243 to the power of 1/5 = 3 because 3*3*3*3*3 = 243
243
NO!!! Remember 3^(5) = 243 Hence 243^(1/5) = 3
243 x 3 = 729
243
It is only 3 that is a prime factor of 243
243
The positive integer factors of 243 are 1, 3, 9, 27, 81, and 243 The factor pairs of 243 are (1, 243), (3, 81), and (9, 27).
This sequence is based on a decreasing exponent and increasing base. 64 is 2^6, 243 is 3^5, 256 is 4^4 and 125 is 5^3. The next number is then 6^2 or 36.
