I need help i am dumb

B) 9

Step-by-step explanation:

You are not dumb. You just probably don't know how to solve this.

When you have the same base (3) raised to x exponent, and these bases are dividing each other, you put the same base and subtract exponents.

Another way of looking at this is;

You're not dumb, it's just a small matter of learning.

First, we have to solve the exponents by multiplying them to their exponents.

3^4 = 3 x 3 x 3 x 3

3^4 = 81

3^2 = 3 x 3

3^2 = 9

Therefore, our new fraction is 81/9.

Lastly, we just need to simplify it.

81/9 = 9

That means your answer would be B.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
