Question

The scientific notation for $0.00016$ is _________.

Answer 1

Scientific notation:

1. Scientific notation is used to represent extremely large or extremely small numbers by multiplying a single-digit integer by 10 raised to the power of the exponent.
2. If the number is very large, the exponent is positive; if the number is very small, the exponent is negative.
3. Given number is $0.00016$

Move the decimal point up to four positions to the right of $0.00016$.

To make the number 1.6, the decimal is moved four spaces to the right.

We use a negative exponent here since the values are less than $10$ and the decimal is shifted to the right.

$\Rightarrow 0.00016=1.6\times {10}^{-4}$

Hence, the scientific notation for$0.00016$ is $1.6X{10}^{-4}$.
