1. A?

OpenStudy (ashley1nonly):

4^11 for the first so A

OpenStudy (ashley1nonly):

on number two you would move the x^-8 to the bottom

OpenStudy (ashley1nonly):

so now you have 7times6x^3/x^8

OpenStudy (ashley1nonly):

wha you can do is elimate the top x and make the bottom x got to x^5

OpenStudy (ashley1nonly):

so now you have 7 times 6/x^5

OpenStudy (ashley1nonly):

42/x^5

OpenStudy (ashley1nonly):

A

OpenStudy (anonymous):

OpenStudy (ashley1nonly):

4.) is 5.6 times 10^12

OpenStudy (ashley1nonly):

5.) 6.3 times 10^-13

OpenStudy (anonymous):

3. C?

OpenStudy (ashley1nonly):

oh sorry skipped that one

OpenStudy (ashley1nonly):

lets do process of elimintation

OpenStudy (ashley1nonly):

we now that we can multiply the numbers -2 time 3 times2 -12

OpenStudy (ashley1nonly):

so no A we no that the y stays the same since it doesnt have any common friends so no C

OpenStudy (anonymous):

B

OpenStudy (anonymous):

?

OpenStudy (ashley1nonly):

where did you get the 72

OpenStudy (ashley1nonly):

8 times4 =32 8+4 =12

OpenStudy (anonymous):

multiply -2 time 3 times -12

OpenStudy (ashley1nonly):

they tried to trick you thinking you would multpliy the y 9 times x 8 which is wrong because they are apart of two different varaibles

OpenStudy (anonymous):

oh

OpenStudy (ashley1nonly):

so now that that is gone whats left

OpenStudy (anonymous):
