3x2y
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
8x to the second power is 64x2
what is 7x to the third power + 6x to the second - 2
eight to the second power equal to 64
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
They are: x and y and the expression can be simplified to 6xy
3x2y
12
It is a polynomial in x and y.
3x times 2y = 3x2y In a system of equations, you can only solve for a system if there are the same amount of variables as equations. Since there is only one equation (actually, it is a monomial, but considering 3x2y=0) and there are two variables, x and y, we cannot solve for the variables. The simplest form is 3x2y.
The GCF is 3x2y
Without an equality sign it is not an equation
I will assume that you mean -2xy3+3x2y. Then by "degree" is usually meant the total degree--the maximum sum of exponents of all variables. Here the first term has degree 1+3=4 and the second term has degree 2+1=3, so the degree of the entire expression is 4. It is also a 2nd degree expression in x and a 3rd degree expression in y.
2a to the second power. If you combine the like terms, (a to the second power + a to the second power), it would be the same as 2a to the second power.
3x2y - 4xy + 4x
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
