Question

Evaluate by correctly positioning the decimal point: 42.291 divided by 10^-4

Answer 1

By evaluating correctly the answer is 422910.

Explanation:

Given:

42.291 divided by 10^-4.

Now, evaluating:

`42.291/ 10^(-4)`

Now, we will change the exponent from negative to positive.

`42.291/ (1)/(10^(4))`

Now, we change the division to multiplication.

`42.291* 10^(4)`

And, we will break the exponent.

`42.291* 10* 10* 10* 10`

`=42.291* 10000`

`=422910.`

Therefore, by evaluating correctly the answer is 422910.
