Please see previous question:

Hello, I have two more rational exponent question that I wanted to verify please:

4x^3y^-2

_________

2x^-1y^4

= 2x^4y^6

is this correct?

2nd question:

[w^1 / w^-3]

my answer:

= [w^(1)(-4)/ w ^ (-3)(-4)]

= w^-4 / w^12

= w^12 / w^4

= w^3 / w

Is this right?

Both are wrong. You seem to have no idea at all how to handle exponents.

The answers are

2x^4 y^-6 and w^4.

4x^3y^-2 / 2x^-1y^4 = 2x^3x^1 / y^4y^2=

2x^4 / y^6.

2. W^1 / W^-3 = W^1W^3 = W^4.

RULES:

1. NEVER leave neg. exponents in your

final answer.

2. When multiplying, always add the

exponents.

3. When dividing, subtract the expon.

in the denominator from the exponent in

the numerator and put the results in

the numerator. If the results is neg.,

move it to the denominator as a positive.
