What kind of a number is 64?
Sixty-four is several kinds of number. It is an even number It is a two-digit number It is a square number - the second power of 8 -> 8 * 8 = 64 It is a cubic number - the third power of 4 -> 4 * 4 * 4 = 64 It is a 6th power number - the sixth power of 2 -> 2 * 2 * 2 * 2 * 2 * 2 = 64 It is a superperfect number
What is a solution to these equations X plus Y equals -8 and 2x - y equals 4?
x+y=-8 2x-y=4 y=-x-8 2x+x+8=4 3x=-4 x=-4/3 -4/3 + y= -8 y = -8 + 4/3 y= -6 2/3
What are the 2 solutions for x if 3x2 plus 2x-8 equals 0?
3x2+2x-8=0 Delta = 22-4*3*-8= 100 So x = (-2 + sqrt(100))/(2*3) or x = (-2 - sqrt(100))/(2*3) x = 4/3 or x=-2
How can you use 2 times 8 to find 4 times 8?
You can use 2*8 to find 4*8 by solving 2*8, then multiplying it by 2. This is equivalent to 4*8, or 32.
How do you use continuous division to find the GCF?

How can you use 4 times 7 to find 8 times 7?
You can use 4x7 to find 8x7 because 4 x 2 is 8, and you are simply doubling one of the numbers you are multiplying, (4 to 8) and so multiply your answer from 4x7 by 2 to get the answer to 8x7. 4x7 is 28 and 8x7 is 56, and 28 x 2 is 56.

How do you find the cube root of -8?
Don't know how you find it but I guess the answer is -2. -2 x -2 =4 4 X -2 = -8
How do you use 2 4 6 8 to make one?
8 / (6-2+4) = 8/8 = 1/1 = 1
How can you use doubling to find the product of 8 times 8?
double 88 x 2 = 16 (8 x 2) double 1616 x 2 = 32 (8 x 4) double 3232 x 2 = 64 (8 x 8)
What two simpler problems can you use to find 4 times 22?
22 * 2 =44 44 * 2 = 88 Partitioning 22 is not an option since that leads to 3 problems, not 2: 4 * 20 = 80 4 * 2 = 8 and 80 + 8 = 88
Need to use the same 4 numbers10 different times to come up with answers from 1 to 10 using these numbers 2 4 6 8?
8 - 4 - 6 / 2 = 1 (6 + 2) / (8 - 4) = 2 6 × 2 / (8 - 4) = 3 4 × 8 / (6 + 2) = 4 6 - 8 / 4 × 2 = 5 6 + 2 × 4 - 8 = 6 (6 + 8) / (4 - 2) = 7 8 + 6 - 2 - 4 = 8 8 + 4 - 6 / 2 = 9 8 - 6 + 2 × 4 = 10
What does one half plus two eighths equal?
You need to find a common denominator.First of all, 2/8 can be simplified as 1/4.Next, convert 1/2 to fourths: 1/2 = 2/4.Once you do this, addition is fairly simple: 1/4 + 2/4 = 3/4.You can also do this without simplifying the original fraction: 1/2 + 2/8 = 4/8 + 2/8 = 6/8. This simplifies to 3/4.You need to find a common denominator.First of all, 2/8 can be simplified as 1/4.Next, convert 1/2 to fourths: 1/2 = 2/4.Once you do this, addition is fairly simple: 1/4 + 2/4 = 3/4.You can also do this without simplifying the original fraction: 1/2 + 2/8 = 4/8 + 2/8 = 6/8.
