(d) raise a to the power of mn
(e) raise a to the power of 1/(mn)
- When we add a+jb to its conjugate, we get
(a)a^2 +b^2
(b)a^2 −b^2
(c) 2a
(d) 2b
(e) 4ab
- Consider this general equation, where p,q,r, and s are all positive real numbers:
(px+q)(rx+s)= 0
What is the solution set X for this equation?
(a)X= {q/p,s/r}
(b)X= {−q/p,−s/r}
(c)X= {pq,rs}
(d)X= {−pq,−rs}
(e) We need more information to answer this
- We can tell right away that a fraction is in lowest terms if
(a) its numerator is “cleanly” divisible by its denominator.
(b) its denominator is “cleanly” divisible by its numerator.
(c) its numerator is a product of primes.
(d) its denominator is a product of primes.
(e) its numerator and denominator are both prime.
- Imagine that we’re working exclusively in the hexadecimal system. What numeral
represents a quantity one less than 100?
(a) 9F.
(b) 7F.
(c) AF.
(d) FF.
(e) There is no such numeral as 100 in the hexadecimal system, so this question is
meaningless!
- The commutative law for addition can be applied to finite sums of
(a) natural numbers only.
(b) integers only.
(c) rational numbers only.
(d) irrational numbers only.
(e) real numbers.
