Answer 2

The standard form of the number 2.35 × 10^{-3} is:

A) 0.00235

Explanation:

We are given a number in scientific notation as:

`2.35* 10^(-3)`

we know that if the power of 10 is negative then in the standard form the decimal is shifted to the left of the actual decimal depending on the power of 10.

Here the power of 10 is -3.

This means that the decimal is shifted 3 places to the left.

Hence, the number in standard form is: 0.00235
