Answer:
{1, 3, 5, 6, 7, 9}
Step-by-step explanation:
A u (B n C)
First we look at
(B n C)
n indicates intersects. Intersects means the common. The common number in B and C, we have
{6}
Now A u {6}
u means union. That is, joining both sets together, hence, we have
{1, 3, 5, 6, 7, 9}
A u (B n C} gives {1, 3, 5, 6, 7, 9}
Answer:
4
Step-by-step explanation:
This is a substitution question
So we will have to substitute the value of x given into the given question
f(x)=8^x
And x is given as 2/3
So let's get to work
8^2/3 which means that cube root of 8 then square the answer
(3√8)^2
Cube root of 8 is 2
So we will have to square 2 to get 4
Therefore the final answer is 4
