Select the two equivalent expressions. A. m + 2m + 8 + m + 9
B. 10 + 3m + m + 6
C. 4(m + 16)
D. 4(m + 4)

B. and D.

B. 10m+3m+m+10+6=4m+16

D. 4(m+4)=4m+16

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
