Detailed Solution

For the size of a bacteria being 0.0000005m, the number in standard form of exponents and power is 5× 10 −7 m  .
Given that,
Size of bacteria = 0.0000005m.
Standard form is a way of representing a number as a product of decimal numbers and powers of 10.
The number ‘0.0000005’ contains 6 zeros after the decimal point and is less than 1.
So, the power is negative in nature.
If we include the first non-zero digit, the power of 10 is -7.
Therefore, the size of bacteria having 0.0000005m in standard form is 5× 10 −7 m  .
