13) 16d^8c^8

Other) 72n^-5r^-1

Step-by-step explanation:

13) 2x8=16

d^3*d^5=d^8

c^6*c^2=c^8

16d^8c^8

Other problem: (hard to read, so check my numbers)

8x9=72

n*n^-6=n^-5

r^-4*r^3=r^-1

72n^-5r^-1

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
