Math Question.

For homework we have to check other peoples papers. Lol. I don’t know? But I dont want to mark this question wrong and I’m not sure of the answer.

Question: 5w^2 (6w - 4)

[by the way 5w^2 means 5w to the 2nd power]

He said already simplified. Is this right?

Next Question: -3k^4 * 2k^2

[-3k^4 is negative 3k to the fourth power and 2k^2 is 2k to the second power]

[the * is multiplacation sign]

Hope it makes sense. Thanks.

Answer #1

The second question (I think?) should be -6k^6 The first should be 30w^3 - 20w^2 I think. But I haven’t done this sort of math in years.

Answer #2

second question is -6k^6 first question is I believe is already simplified.
