Question

Addison studies a tarantula there is 30 millimeters long. Suppose she used a microscope to magnify the spider by 4×10 to the second power. How long will the spider a peer to be.

Answer 1

we know that

If the microscope magnify the spider by
`4*10^(2)`

that means that magnifies the spider 400 times

so

Multiply the length of the tarantula by
`4*10^(2)`

`30mm*4*10^(2) =30mm*400=12,000 mm`

therefore

the answer is

the spider under such microscope he will appear to be 12000 mm
