1. Which exponent makes the statement true? 1/5^9 = 5^?

a. 9
b. -9
c. 1/9
d. - 1/9

2. y^5 x y^14 =

a. 2y^19
b. y^60
c. y^19
d. 2y^60

3. w^12/w^18 =

b. 5^2
c. 5^3
d. 5^4

Answer 1

Remember your basic rules for exponents.
1/a^n = a^-n
a^m * a^n = a^(m+n)
a^m / a^n = a^(m-n)

Now apply them to these simple problems.
