64

-8 and -8

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.

-8 and -8

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

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