How can you get 100 using the numbers 1 4 8 9?
9 squared = 81 4 squared = 16 (81)(16) = 1296 (1296)(8) = 10368 sq. root of 10368 = 101 101 - 1 = 100
Can you make a square from the factors of 81?
9 x 9 = 81 9 squared = 81 3 squared times 3 squared = 81
How did you find the factors of x squared minus eighty-one?
x2-81=(x-9)(x+9) Factors: x-9, x+9
What number is 2 didgets lower than 9 squared and have 26 and 6 as factors?
9 squared is 81. Two digits lower than 81 is 79. 79 is a prime number. Its only factors are one and itself. That does not compute. 78 has 26 and 6 as factors. 78 is three digits lower than 81. That does not compute.
What numbers have 5 or less factors?
16, 81, 625 and so on. Prime numbers to the 4th power.
What is nine squared times two minus four squared?
81 x 2 - 16 = 146
What is the answer on 4 x squared over 81 equals 1 minus 16 x squared over 25?
4x2/81 = 1 - 16x2/25100x2 = 25*81 - 16*81x21396x2 = 2025x2 = 2025/1396x = +/- 1.2044, approx.
What is 9 squared 16 squared?
9 squared is 81 and 16 squared is 256
How do you factor the expression x squared minus 81?
x2-81 = (x-9)(x+9)
What is 9x squared minus 6xy plus y squared minus 81 factored as?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
How do you factor 81 minus 25u squared?
(9 - 5u)(9 + 5u)
What is the solutions to y plus 3 squared minus 81?
78 minus78
What is the solutions to y plus 2 squared minus 81?
79, -79
Factor 9x squared minus 6xy plus y squared minus 81?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
What is 9x squared minus 6xy plus y squared minus 81?
The answer? There is no "answer" There cannot be an answer because they are all different. In order to make calculations, the variables have to be the same. x squared, xy, y squared are the variables, and none of them match. Therefore your "answer" must look like this: 9x squared - 6xy + y squared - 81. Hope I Helped :D
What is the 9th squared number number?
81
How do you factor 2xcubed minus x squared minus 162x minus 81?
I believe it is prime as you have written it. change the end to + 81 and it factors as (2x - 1)(x-9)(x+9)
