Question

help please

Answer 1

What Do Yhu Think?

Answer 2

To "divide" exponents with the same base, simply subtract the exponents.
a^9/a^4
a^9 - 4
What does 9-4 equal?

Answer 3

5

Answer 4

So.. what do you think the answer is now? :P

Answer 5

B, can you help me with more?

Answer 6

Not quite. The fraction sign in this case isn't necessary after you subtract the exponents. So your answer is A. Make sense?
a^9/a^4
a^9 - 4
a^5 <-- Answer.

Answer 7

And yes I can. :) Close this one question and I'll help on another post.

Answer 8

i i meant a

Answer 9

Product of Powers property: When you multiply powers with the same base you just have to add the exponents. Ex. x^a * x^b = x^a+b

Power of a product property: When you raise a product to a power you raise each factor with a power.

Quotient of Powers property: When you divide powers with the same base you just have to subtract the exponents.

Power of a power property: To find a power of a power you just have to multiply the exponents. Ex (x^2)^4 = x^2 * 4

Answer 10

Which one describes the question?

Answer 11

C

Answer 12

What are we doing with the exponents in the problem? Subtracting? Multiplying? Adding?

Answer 13

multiplying

Answer 14

Which property deals with multiplying?

Answer 15

A again

Answer 16

I should've worded that differently. xD
A deals more with addition.
B deals with multiplication.
C deals with subtraction.
D deals with multiplication.

An example of B would be: (xy)^2 = (xy) * (xy) = (x * x) * (y * y) = x^2y^2
An example of D would be: (x^2)^4 = x^2*4
Which one (B or D) resembles the question?

Answer 17

b

Answer 18

Still no. It's not A or B and C deals with subtraction.

Answer 19

oh so d

Answer 20

Yup!

Answer 21

Answer 22

I'll help as much as I can.

Answer 23

Apply exponent rule: \[(\frac{ a }{ b })^{-c} = (\frac{ b }{ a })^{c}\] =
\[(\frac{ 3 }{ c })^{2}\]
=
\[\frac{ 3^2 }{ c^2 } \]

What does 3^2 equal?

Answer 24

9

Answer 25

We're left with 9/c^2.
