Describe and correct the error in simplifying 5x^7 * 2x^4
5x^7*2x^4= 7x^7+4
=7x^11

5x^7 x 2x^4 = 10x^11

Step-by-step explanation:

Let's disregard the exponents for now and focus on the variables.

5x x 2x is 10x

As for the exponents:

^7 x ^4 = 7 + 4 = 11

Answer is:

10x^11

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
