Simplify 3 x times the fraction 1 over x to the power of negative 4 times x to the power of negative 3.

N76 [4]

Answer:

3x^2

Step-by-step explanation:

Given:

(3x) * {(1/x)^-4 }* (x^-3)

=(3x) * {1 ÷ (1/x)^4} * {1/x^3}

=(3x) * {1(x/1)^4} * (1/x^3)

=(3x) * (x^4) * (1/x^3)

=(3x) (x^4) (1) / x^3

Multiply the denominators

=3x^5 / x^3

Can also be written as

=3*x*x*x*x*x / x*x*x

Divide the x

= 3*x*x / 1

=3x^2

3p . (2+k) = 6p + 3pk

pashok25 [27]

$3p* (2+k) = 6p + 3pk$

Subtract $6 p + 3 pk$ from the both sides:

$3p(2+k) -(6p+3pk) = 6p+3pk-(6p+3pk)$

$= 3pk(2+k) - 6p-3pk = 0$

Factor $3p(2+k) - 6p - 3k$

Factor out common term $3p$

$= 3p(k-k+2-2)$

refine:

$0 = 0$

true for all $p$

hope this helps!
