OOH! This is what I have for homework tonight. :) so, the prime factorisation for 8r3 (im asuming that it is 8r to the 3rd) is: 2,2,2,r,r,r and 2r2 is: 2,r,r. so the similar numbers are 2,r,r. So your answer is 2r2 (2r squared)
8r3 - 64r2 + r - 8
SIMPLE! First, you do this: x8mx2y2=7y+8r3
quintic
r2+r2 = 2r2
2
well the formula is frequency=1.44/(r1+2r2)c1
x2 + y2 = 2r2
Yes. The proton field is E = d/dr ezc/2r = -ezc/2r2 .
The GCF is 6.
The volume of a cube is L3. The volume of a sphere is 4/3 π r3 . If L=2r, Vcube=8r3. Comparing the volume of the cube with a side 2r and a sphere with a diameter of 2r where the r's are equal gives us: Vcube/Vsphere= (8r3)/(4/3 π r3 ) or (8x3)/(πx4) As π roughly equals 3 the equation simplifies to: Vcube/Vsphere=2 or a cube with its side equal to the diameter of a sphere has a volume approximately twice that of the sphere.
The GCF is 9.
The GCF is 4.
