Question

please help me!!!!!!!!!!!

Answer 1

7. x7 • y3 • x8 • y2 (1 point)

Answer 2

Remember, \(a^ba^c = a^{b+c}\)

Answer 3

no:(

Answer 4

For example, \(x^7x^8 = x^{7+8} = x^{15}\)

Answer 5

oh i get that do i do the same for that questions

Answer 6

Yeah.

Answer 7

thanks can you help me with a few more or no?

Answer 8

Sure, just post a new question.

Answer 9

4. 120m16/ 45m8

Answer 10

\(\dfrac{a^b}{a^c} = a^ba^{-c} = a^{b-c}\)

Answer 11

\[\dfrac{120m^{16}}{45m^8} = \dfrac{120}{45}\cdot m^{16} m^{-8}\]

Answer 12

Is this clear? No?

Answer 13

yes it is thank you

Answer 14

You're welcome.

Answer 15

8b3/20b3

Answer 16

Since the power of b is both same in numerator and denominator, they cancel out so this leave you 8/20. Reduce it.

Answer 17

9. Explain the process you would use to simplify 5^3*5^2/5^7 .

Answer 18

Got to go sorry. @nubeer @some_someone @e.mccormick

Then there was another problem when dividing he showed subtracitng them.

All this problem has is both of those in one question.

Answer 22

thank you soo much

Answer 23

No problem.

Answer 24

A lot of math is like this. You learn one rule. Then another. And another.... and so on. Then they have you use those rules together. Eventually, you are using dozens of rules all at once, theorems and lemmas galore, all without realizing it. Take multiplication. It is defined as repeated additions. Every time you multiply you use that rule and do not think about it.

Answer 25

thanks you :)

Answer 26

np. Have fun!
