Answer:
(a)
(b)
(c)
(d)
(e)
(f)
Step-by-step explanation:
(a)
we can factor numerator and denominator
and then we can simplify it
Numerator:
Denominator:
now, we can replace by factors
now, we can cancel and simplify it
(b)
we can factor numerator and denominator
and then we can simplify it
Numerator:
Denominator:
now, we can replace by factors
now, we can cancel and simplify it
(c)
we can factor numerator and denominator
and then we can simplify it
Numerator:
Denominator:
now, we can replace by factors
now, we can cancel and simplify it
(d)
we can factor numerator and denominator
and then we can simplify it
Numerator:
Denominator:
now, we can replace by factors
now, we can cancel and simplify it
we get
(e)
we can factor numerator and denominator
and then we can simplify it
Numerator:
Denominator:
now, we can replace by factors
now, we can cancel and simplify it
(f)
we can factor numerator and denominator
and then we can simplify it
since, 73 can not be factored
now, we can plug it
now, we can cancel and simplify it
