Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long,
AysviL [449]

We have been given that Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long. We are asked to find the length of chain of bacteria in centimeters.

We know that 1 millimeter is equal to 0.1 centimeter.

To convert 10 milllimeters into centimeters, we will multiply 10 by 0.1.

\text{Length of bacteria in cm}=10\text{ mm}\times \frac{0.1\text{ cm}}{\text{1 mm}}

\text{Length of bacteria in cm}=10\times 0.1\text{ cm}

\text{Length of bacteria in cm}=1\text{ cm}

Therefore, the chain of the bacteria is 1 cm long.

Someone pls help! <br> write the expression in radical form. 2 4/5
kipiarov [429]

Answer:

  \sqrt[5]{2^4}

Step-by-step explanation:

Maybe you want 2^(4/5) in radical form.

The denominator of the fractional power is the index of the root. Either the inside or the outside can be raised to the power of the numerator.

  2^{\frac{4}{5}}=\boxed{\sqrt[5]{2^4}=(\sqrt[5]{2})^4}

__

In many cases, it is preferred to keep the power inside the radical symbol.
