Answer:
Step-by-step explanation:
first distribute the ^3, -3^3=-27, for the variables, (x^y)^3=x^(3y) so (b^2)^3=b^6 and (c^-6)^3=c^-18. now we have . Next we have to get rid of the negative in c^-18. x^-y=1/x^y so c^-18=, plug it in and you get
p ≥ 7/4
1/4
25 people took a vitamin and still got the flu and the total number is 100 so the fraction is 25/100 which can be reduce to 1/4
2/2
