Which expression is equivalent to 28 + 7? A 7(4 + 1) B 4(7 + 1) + C 4(7 + 3) D 7/4 + 7) to search o Be 9

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!
