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
