Square root of -45 = (-45)1/2 = (-3x3x5)1/2 = 3(-5)1/2 = 351/2i

That 8 might equal D. Trashed. "Eight Equals D" is: 8=D Which is a penis smiley -.- ~ Skullcandy88

To figure this out you should first express the numbers as the product of their prime factors: 27 = 3x3x3 45 = 3x3x5 The next step is to identify any common prime factors. Both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus 9 is the HCF of 27 and 45.

There are two ways to why the prime factorization for 45 equals 3x3x5. First of all, you may start with multiplying it. Start with 3x3; which equals nine or 9. Then 9x5 equals 45. the other way is that you may break it down, starting from 45. first you find 2 factors that you can multiply to receive the answer or product of 45. If you said 9x5 you are correct. So therefore you below the number 45 you may write the equation 9x5. Then you check if any of the numbers can be reduced or simplified. Let's start with the 5: can you find any factors of five? No, so you bring down the 5. How about 9? Yes, 3x3. Are there any others? No, there are no others, unless you include 9x1. But that's too easy. Below the 9 and beside the 5 write the multiplication sign, then 3x3. It should look something like this: 4 5 ^ 9 x 5 ^ ^ 3 x 3 x 5 sorry if the computer distorts the prime factorization tree.

Factor both numbers into primes. Circle any common primes and multiply them/ 45=3x3x5 54=2x3x3x3 3x3=9 GCF

The answer is 45 135=3x3x3x5 315=3x3x5x7 each number has at least 2 3s and one 5 3x3x5=45 Your welcome
