Answer: 0.000000315m
Explanation:
Radius of each bacterium in a petri dish
= 3.15 × 10^-7
According to the law of indices,
10^-7 = 1/10^7 = 1/10000000
Therefore, 3.15 × 10^-7 will then be:
= 3.15 × 1/10000000
= 0.000000315m
Therefore, the radius of the bacterium written as a decimal number in standard form will be 0.000000315m
