Simplify the expression 32y - 5y?
27
How do you factor 64x to the third power minus 27y to the third power?
(4x - 3y)(16x^2 + 12xy + 9y^2)
What is the smallest positive integer n such that 2n is a perfect square and 3n is a perfect cube?
n=72 satisfies the relation. 2*72 = 12**2, and 3*72 = 6**3. The only question is whether or not that is the smallest integer that will do so. All perfect squares of which 2n is a factor are of form (2x)**2 = 4x**2, with n= 2x**2. Similarly all perfect cubes of which 3n is a factor are of form (3y)**3 = 27y**3 with n = 9y**3. So, we need integers x and y such that 2x**2 = 9y**3. If the integers x and y are the smallest that satisfy the equation, then we have the smallest n. It doesn't work for y = 1, or any other odd number. If y = 2, n = 72. There is a number x =6 which satisfies the relation. Since y is smallest possible, then n=72 is the smallest positive integer that satisfies the relation.
What is y times 7y?
Yx7y = 7y2 (squared )
How do you factor y cubed plus 27z cubed?
(y + 27)(y^2 - 27y + 729)
GCF of 27y 54y3?
Since 27y is a factor of 54y3, it is automatically the GCF
How do you factor 8x³-27y³?
35
How do you solve this problem 5 times 3y plus 1 plus 12y-1?
5*3y+1+12y-1 = 15y+1+12y-1 = 27y.
What is the LCM 63x and 27y?
189xy
What is the gcf of 27y and 54y3?
Since 27y is a factor of 54y3, it is automatically the GCF.
Simplify the expression 32y - 5y?
27
What is y plus 3 to the third power plus 2 divided by 4?
It depends on where there are parentheses, if there are any. y + 33 + 2/4 = y + 27.5 (y+3)3 + 2/4 = y3 + 9y2 + 27y + 27.5
How do you solve this 7y-4 plus y plus 5 equals 28?
7 y - 4 + y + 5 = 287 y + y + 1 = 288 y + 1 = 288 y = 27y = 27/8y = 3.375
Factor 9x-27y by separating the GCF?
9(x - 3y)
Which is the common factor of the expression 6y2 27y?
It is: 3y and y
