This is a easy question just not sure what’s to do lol

9 × 10⁻⁴

Step-by-step explanation:

A number in scientific notation has the form A × 10ⁿ.

A is a number from 1 to 10, but not 10 itself and is called the coefficient.

n is an integer and is called the exponent.

10 000 has four zeros, so the exponent is 4.

However, your number is 9 ten thousandths, or 9/(10 000).

When the powers of 10 are in the denominator, the exponent is negative. In this case, the exponent is -4.

In scientific notation,

9 ten thousandths = 9 × 10⁻⁴

what's the question?

step-by-step explanation:

there is no question.
