Answer 2

3.8 × 105

Explanation:

Add to find the total number of platelets and white blood cells in a microliter of blood.

First, write the number of white blood cells in scientific notation.

Now that both numbers are written in scientific notation, compare the exponents. Since both exponents are not the same, rewrite 9.3 × 103 as 0.093 × 105. Now the numbers multiplied by the powers of 10 can be added while keeping the power of 10 the same.

So, there are about 3.8 × 105 platelets and white blood cells in a microliter of blood.
