How do you display a square root symbol using Excel?
Alt+251 -- To show the symbol you need to hold alt and press 251 on the numpad. Just in case you are meaning to find the square root of a number then you only need the function SQRT(~number~). Also, it looks kind of like a check mark. So, as an alternative, you can also write square root as "^(1/2)" or "^0.5" or just "^.5"
What is the name of the number with a 1 followed by 100 zeros?
A googol. An alternative spelling is google, which is where the search engine got its name from.The original definition of googol was: write 1 and then write zeros until you get tired, but it became standardised at 100 zeros aftert the 1.A googolplex is 1 followed by googol many zeros
Twice a number decreased by 9 is greater than 11 what is the number?
IF the question means: What number, multiplied by 2, and reducing the answer by 9, gives a result that is greater than 11?ANSWER: Any number greater than 10.Let's try 11.2 x 11 = 22.22 - 9 = 13, which is greater than 11.But if we try 10 ...2 x 10 = 20.20 - 9 = 11, but 11 is not greater than 11! So we need a higher number than 10.Try it for yourself with ANY number greater than 10!-----------------------------------------------------------------------------------------Alternative answer.If the question means "What number decreased by 9, and then doubled, produces a number greater than 11?"...... then work it out this way, working backwards:What number is greater than 11?We could say '12' is greater than 11.Half of 12 is 6. Add 9 to 6 = 15.So, now, let's try 15.15 decreased by 9 is 6.Twice that number is .... 12 (2 x 6), which is greater than 11!But this would work for ANY number from 15 upwards!
What is the greatest common factor of 121 and 132?
121: 11-11 132: 2-2-3-11 Great common factor: 11 Method(s) used: # (used) The method to find the greatest common factor of numbers is to find the prime factorizations of each one, select all matching prime factors, and then multiply. # An alternative method is to find all of the factors of each, and then select the greatest number that appears in each list. # The final method only applies to some numbers; if one of the number is a factor of the other, then that number is the greatest common factor. This is because all numbers are factors of themselves, and that is their greatest factor. If it is also a factor of the other number, then it is definitely the greatest common factor.
