b) m = 0, n = -3
c) m = -3, n = 0

4. reduce to lowest terms.

6a^2b^3

8ab^4

a) 3b/4a
b) 3a/4b
c) 3/4ab

5. reduce to lowest terms.

3-k

k-3

a) -1
b) 1
c) -1/3

correct option is (C)

Step-by-step explanation:

Q 1.)

To find excluded values, we equate denominator of above expression to zero:

solve above expression by middle term splitting,

factor out GCF,

factor out the common terms,

Hence, the correct option is (C)

Q 2.)

To find excluded values, we equate denominator of above expression to zero:

subtract 1 from both the sides,

divide both the side by 4,

Hence, the correct option is (B).

Q 3.)

To find excluded values, we equate denominator of above expression to zero:

Take common factor out 'm',

Hence, the correct option is (B)

Q 4.)

To reduce tom lowest term, cancel out the common denominators term with numerators;

Using the low of exponent \frac{a^n}{a^m}=a^n-m,

so,

Hence, the correct option is (B)

Q 5.)

To reduce tom lowest term, cancel out the common denominators term with numerators;

Hence, the correct option is (A)
