For this case we have the following expression:

(ab ^ 2 + 4a ^ 2 + 6a ^ 2b ^ 2) - (- ab ^ 2 + 2a ^ 2b ^ 2 + 4a ^ 2) =

We must simplify taking into account that:

- * - = +\\- * + = -

So, we have:

ab ^ 2 + 4a ^ 2 + 6a ^ 2b ^ 2 + ab ^ 2-2a ^ 2b ^ 2-4a ^ 2 =

We add similar terms:

ab ^ 2 + ab ^ 2 + 4a ^ 2-4a ^ 2 + 6a ^ 2b ^ 2-2a ^ 2b ^ 2 =\\2ab ^ 2 + 4a ^ 2b ^ 2

Answer:

2ab ^ 2 + 4a ^ 2b ^ 2

PLEASE HELP ME!!<br> .<br> . Not sure how to do thisssss
tino4ka555 [31]

√72 = √4 * √18 = 2√18. Therefore her answer is incorrect.

√72 = √4 * √9 * √2 = 6√2.

Since √2 is approximately 1.41,

6 * 1.41 = 8.46 = 8.5 (nearest tenth).
