Question

Find the quotient. 48j 5 k 2 ÷ (-3j 3 k) A) -16j2k B) -16j3k2 C) -16j3k

Answer 1

The answer is A because the question 48j5k2 / (-3j3k) you first turn all the positive numbers to negative and all negative to positive. -48j5k2 / (3j3k) Dividing a positive and a negative equals a negative: (+) divide (-) = (-) then calculate the quotient 48j5k2 / (-3j3k) =16j2k

Answer 2

For this case we must find the quotient of the following expression:

$\frac {48 * j ^ 5 * k ^ 2} {- 3 * j ^ 3 * k} =$

We have to:

$\frac {48} {- 3} = - 16$

By definition of power properties we have:

$\frac {a ^ m} {a ^ n} = a ^ {m-n}$

So so:

$\frac {48 * j ^ 5 * k ^ 2} {- 3 * j ^ 3 * k} = - 16 * j ^ {5-3} * k^{2-1}=-16*j^2*k$

Answer:

Option A
