-8 and -8
64
to factor (x2-16x+64), you need to find two number whose product is 64 and whose sum is 16. These two numbers are 8 and 8. (x2-16x+64)=(x-8)(x-8)
This problem actually has no solution. Any two numbers that will add to 6.5 will be too small to produce a multiple equal to 64. However, for problems like this in general, writing the question as a formula might help you solve it. 1. Assume the numbers are x and y. 2. Write two equations (two unknowns and two equations gives you enough information to solve). -The first part, "two numbers added equal 6.5" can be written as x + y = 6.5 -The second part, "two numbers multiplies equal 64" as xy = 64 3. Manipulate the equations to solve. For example: y = 64/x x + y = x + (64/x) = 6.5 4. Solve for x, and then use x to find y using either of the original formulas.
The sum of the prime numbers 11 and 53 equals 64.
44
These are the pairs of numbers that when multiplied are equal to 64: (1, 64) (2, 32) (4, 16) (8, 8)
-8 and -8
64
8 times 8=64
Any two numbers that when multiplied, equal 8^2 (64). So, 2 and 32 work. So do 1 and 64. And 4 and 16. And .5 and 128

You'll need six. 2 x 2 x 2 x 2 x 2 x 2 = 64

2*5 = 10 so 26 * 56 = 106 = 1000000 So the two numbers are 26 = 64 and 56 = 15625
