x^3(2x^-2+4x) simplifies too what? and explain how please.?

Answer 1

what you have is something like
a(b+c)

the solution is
ab+ac

(x^3)(2x^-2)+(x^3)(4x)
now to multiply x^a * x^b you get x^(a+b)

2x^((3+(-2))+4x^(3+1)

2x+4x^4

Answer 2

x^3(2x^(-2)+4x) = 2x+4x^4
This is a question that requires simple distributive law and exponent law. x^3 * 2x^(-2) = 2x, since when multiplying exponents with the same base you would add the exponents ( ie. -2 + 3 = 1). Then,
x^3 * 4x = 4x^4 for the same reason (ie. 3+1=4).

Answer 3

That equals 2x+4x^4 which equals to 2X(4X^3+1) thats about it for that one

Answer 4

x^3(2x^-2+4x) = x^3 ( 2/x^2 +4x) = 2x + 4x^4

Answer 5

(x^3)(2x^-2) + (x^3)((4x^1) =
2x^(3-2) + 4x^(3+1)=
2x^1 + 4x^4=
2x + 4x^4

It's the distributive property of multiplication to multiply out the terms, and then you add exponents when you multiply the terms.

Answer 6

x^3(2x^-2+4x)
4x^4 + 2x

Answer 7

how many x^2s can we've? from 3x we get no x^2s from -4x(x + 2) we get -4x^2 from -3(x^2 -x) we get -3x^2 so in entire we've (-4 + -3)x^2 = -7x^2 how many 'x's can we've? from 3x we get 3x from -4x(x + 2) we get -8x from -3(x^2 - x) we get (-3)(-x) = 3x so in entire we've (3 + -8 + 3)x = (6 - 8)x = -2x So the respond is A. -7x^2 - 2x IPOD: the unique cost became into extra beneficial than $one hundred sixty, in certainty 20% extra. to characteristic 20% to $one hundred sixty, i could multiply one hundred sixty * a million.20 = one hundred sixty + 32 = $192.

Answer 8

x^3(2x -2 +4x)
2x^4 -2x^3 +4x^4
6x^4 -2x^3
24x^3 - 6x^2
72x^2 -12x
144x -12x
132x =0
x= -132

Answer 9

4x^4 + 2x

distribute and multiply
