Question

The coefficient in $6.65\times {10}^4$ is_________

Answer 1

Scientific notation :

Scientific notation allows us to express very large or very small numbers in a convenient way. This notation uses a coefficient (a number between 1$1$and $10$) and a power of ten sufficient for the actual number.

Here, the coefficient is $6.65$ and the expoent is ${10}^4$.

Therefore, the coefficient in $6.65\times {10}^4$ is $6.65$
