The number with a prime factorization of 3^4 is _____.
oksano4ka [1.4K]

I think 81 is composite and is 9 squared. 81 = 1 x 81, 3 x 27, or 9 x 9. Factors of 81: 1, 3, 9, 27, 81. Prime factorization: 81 = 3 x 3 x 3 x 3 which can also be written 3⁴. Since √81 = 9, a whole number, 81 is a perfect square. Even though it has other factors, the only multiplication fact we use is 9 x 9 = 81.

3. consider rolling a single die. we get the number d of the die. (10 points) a. if i tell you the number is less than 4 (d <
Semenov [28]

The probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.

The probability of an event = The number of favorable outcomes to the event/The total number of possible outcomes.

In the question, we are asked to find the probability of getting an even number, considering rolling a single die, where we get the number d of the die, and the number is less than 4 (d < 4).

For the number d, the total number of possible outcomes, given d is less than 4 in the rolling of a single die is 3 {viz. 1, 2, and 3}.

For the event of getting an even number, from all the possible outcomes, the number of favorable outcomes is 1 {viz. 2}.

Thus, the probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.
