Tanya distributes pencils to students in her class for an upcoming test. the number of pencils she hands out is given by the equation p = 3s, where p is the number of pencils and s is the number of students. if there are 16 students in tanya's class, how many pencils did she distribute?

3

8

18

48

P = 3sp = # of pencils and s = # of students

if there were 16 studentsso s = 16
p = 3s
p = 3(16)
p = 48 <=== 48 pencils

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
