50 x 3 = 150
Assuming your quesiton is Multiply x times 3x times 4, the answer would be 3x squared times 4.
(2x x 3x) x 2 = 12x (2x times 3x times 2)
10
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
50 x 3 = 150
Your question is ambiguous. (3x)^3 times (3x)^3 = 27x^3 times 27x^3 = 729x^6 or, if you meant 3x^3 times 3x^3 = 9x^6
3x^3
Assuming your quesiton is Multiply x times 3x times 4, the answer would be 3x squared times 4.
3x^4
12xy * 3x = 36x2y
3x^5 If these are 5 of 3x multiplied together the it must be (3x)^5 =3^5 times x^5
(2x x 3x) x 2 = 12x (2x times 3x times 2)
Integrate by parts: ∫ uv dx = u ∫ v dx - ∫ (u' ∫ v dx) dx Let u = -2x Let v = cos 3x → u' = d/dx -2x = -2 → ∫ -2x cos 3x dx = -2x ∫ cos 3x dx - ∫ (-2 ∫ cos 3x dx) dx = -2x/3 sin 3x - ∫ -2/3 sin 3x dx = -2x/3 sin 3x - 2/9 cos 3x + c
As an algebraic term it is simply: 3x
It is negative 3x^2.
3x*x = 3x2
