Answer:
first do 9x40 and get your answer then do 18x3 and get that answer and then add to do answers together
Is the goal to simplify? You just need to multiply the exponents for each factor:
(2z^2)^(-3)
= 2^(-3) x z^(2 x -3)
= (1/2)^3 x z^(-6)
= (1/8) x (1/z)^6
= 1/(8z^6)
Answer:
Number of ways chosen cookies = 8 ways
Step-by-step explanation:
Given;
Total number of chocolate chip cookies = 16
Total number of oatmeal raisin cookies = 12
Total number of cookies choose = 3
At least 1 chocolate cookie
Find:
Number of ways chosen cookies
Computation;
Number of total ways = 2³
Number of total ways = 8
If at least on cookie is chocolate cookie,
Number of ways chosen cookies = Number of total ways - 1
Number of ways chosen cookies = 9 - 1
Number of ways chosen cookies = 8 ways
