Answer:
1.5 × 10⁻⁸ m
Explanation:
It is given that,
The width of DNA is approximately 0.0000000025 meter wide.
We need to find 6 times the width of DNA in scientific notation.It can be siply calculated by multiplying 6 and 0.0000000025.
0.0000000025 × 6 = 1.5 × 10⁻⁸ m
Hence, this is the required solution.
