The two answers are -9 and +9.
the eisest way to find square root of something , is to see what number x itself = that number .... so EXAMPLE:what is the square root of 81? this is how you will find it.....so what number x itself gives me 81? it's 9 because 9x9=81 so the square root of 81 is 9
Use your calculator to calculate the square root of 81. Or use trial-and-error, to see which number, when multiplied by itself, gives you 81. (Hint: In this case, it is an integer.)
The number 9 !
The number 9 !
-9 or +9.
Oh, what a happy little math problem we have here! To find the number that, when multiplied by itself 4 times, equals 81, we simply need to take the fourth root of 81. So, the number we are looking for is 3. Isn't it wonderful how numbers can come together to create harmony and beauty?
The number is three.
The number is -81.
It is a composite number, you can get 81 by mulitpling 1*81, 3*27, and 9*9.compositeNo the number 81 is not prime it can be divided by nine.composite
A factor = a number which can be divided into the given number with no remainder Yes. It's the only factor of 81 (apart from 9, 27 and 81 itself).
The number that, when multiplied by itself, equals 1000 is the square root of 1000, which is approximately 31.62. This is because the square root of a number is the value that, when multiplied by itself, gives the original number. In this case, the square root of 1000 is 31.62 because 31.62 multiplied by 31.62 equals 1000.
81 is a composite number as it has factors other than 1 and itself (3, 27 and 9).
