Which choice shows the size range for nanotechnology? 10-9
m to 10-100 m
10-9 m to 10-11 m
10-9 m to 10-7 m
10-9 m to 109 m

here is the

mark brainliest pl

b.-4 units

all you   do is count how many times you move

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!
