Answer:

163125

Step-by-step explanation:

Divide the numbers then divide the exponents. Put them back together once done.

\frac{5.22}{3.2} = 1.63125

\frac{10^{9}}{10^{4}} =10^{5}

To get 163125, I moved the decimal point 5 places to the right since the exponent is 5.

1.63125*10^{5}=163125

julsineya [31]

Answer:

b.) 18(m+2m)

d.) 18m+18(2m)

e.) 54m

Step-by-step explanation:

Given;

total number of Mr Moretti's students = 18

number of mechanical pencils for each student = m

total number of mechanical pencils for all the students = 18m

number of regular pencils for each student = 2m

total number of regular pencils for all the students = 18(2m)

The total number of pencils given to all the 18 students by  Mr Moretti is given by;

T = Total mechanical pencils + total regular pencil

T = 18m + 18(2m)

T = 18(m + 2m)

T = 18(3m)

T = 54m

Therefore, based on the expressions above, the correct options include;

b.) 18(m+2m)

d.) 18m+18(2m)

e.) 54m
