A square has an area of 64 square units. What is the length of each side ?

The length of each side is 8 square units

Step-by-step explanation:

This is because all sides of a square are the same and area is length times width. So, we can just find the square root of 64 which is 8.

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!
