(3x)(x2) = 3x3.
Think of this as (3x1)(1x2). First multiply the numbers: (3)(1) = 3. next multiply the variables: (x1)(x2) = x1+2 = x3 (when you multiply powers with the same base, add the exponents)
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
2x+x is 3x
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
It is: 3x*(x+7)
Assuming your quesiton is Multiply x times 3x times 4, the answer would be 3x squared times 4.
3x squared - x squared = 2x squared
2x2 x 3x2 = 6 x4 (2x)2 x (3x)2 = 36 x4
3x2 can be called "three times x squared", "three x squared", or "three times x to the power of two".
3x2 times x-33 can be simplified to: 3x3 times -27
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
the derivative of 3x is 3 the derivative of x cubed is 3 times x squared
2 squared X 3 squared = 5 squared
The expression 3X divided by X squared can be simplified by dividing the coefficient of X by the coefficient of X squared. In this case, 3X divided by X squared simplifies to 3/X. This is because when dividing by a term with an exponent, you subtract the exponents in the denominator from the exponents in the numerator.
2x+x is 3x
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
3x2 + x = x*(3x + 1)
