Find the geometric mean of 405 and 5?
GM of two numbers is the square root of their product, in this case sqrt 2025 ie 45.
What 2 numbers add up to 45 and multiply to -196?
To find two numbers that add up to 45 and multiply to -196, we can set up a system of equations. Let's call the two numbers x and y. We have the equations x + y = 45 and x * y = -196. By solving these equations simultaneously, we can find that the two numbers are 13 and -15, as 13 + (-15) = 45 and 13 * (-15) = -196.
What is the geometric mean of 3 and 15?
Just use the definition of geometric mean. Multiply all the numbers together, then take the square root. (In this case, it is the square, or second, root, because there are two numbers; for the geometric mean of three numbers, you take the cubic root, etc.)
What times 2 equals 90?
4545 * 2 = 90You can do this in your mind by adding 40 + 40 = 80, then add the two fives 5 + 5 = 10, and add those two sums together. 80 + 10 = 90.
What Times by itself equals 45?
6.708203932499369 x 6.708203932499369 = 45
