D. 2y60

Using the numbers 3, 2, and 4, which of these problems would have a solution of 4?
A. 4 • 2^3/2^3
B. 2 • 2^3/2^4
C. 3 • 2^3/2^4
D. 3 • 2^4/2^4

Solve equation: w^12 over w^18
A. w^30
B. w^–30
C. w^6
D. w^–6

Answer 1

1/5^9 = 5^?
1/5^9 = 5^-9 , by the definition of a^-n

solve the equation: y5 • y14
This is not an equation, but simplified it would be y^19

A. 4 • 2^3/2^3 = 4*1 = 4
B. 2 • 2^3/2^4 = 2*1/2 = 1
C. 3 • 2^3/2^4 = 3* 1/2 = 3/2
D. 3 • 2^4/2^4 = 3*1 = 3

Solve equation: w^12 over w^18
again, this is not an equation, but simplified it would be 1/w^6 or w^-6
