(4x + 7y)(16x2 - 28xy + 49y2)
(4x)3 = 64x3 y0 = 1
The difference of cubes has a formula. (4x - y)(16x2 + 4xy + y2)
really? calculator bud..192..n in case ur wondering 4x4x4=64x3..
If that's + 21, the answer is (8x - 3)(8x2 - 7) If that's - 21, it gets ugly in a hurry.
The GCF is 8x^3
The value of 64x3 + 27 depends on the value of x. If the question required factorisation, but did not ask for it, the answer is: (4x + 3)(16x2 - 12x + 9)
This would have been easier to answer if you had told us what the following choices were, but if they include (4x + 7) or (16x2 - 28x + 49), choose one of them.
if you mean: 3x3 times 4x3 = 12x6if you mean: (3x)3 times (4x)3 = 27x3 times 64x3 = 1728x6 oh and also my penis is 3x
The lowest common multiple of 64 and 16 is 128. 16x8=128 64x3=128 Both the numbers go into 128 evenly, and since 128 is the lowest multiple that they BOTH go into, it is the LCM of both numbers.
There are no real solutions to this equation. Applying the quadratic formula, we find two imaginary solutions.x = 2.315032397181517ix = -2.315032397181517iwhere i is the square root of negative one.If that were 64x3, it would have been (4x + 7)(16x2 - 28x + 49)
