a. 10^3
b. 1/10^3
c. 1/10^(-3)
d. 10^-3

Answer 1

The expression 10^(-3) can be written using a positive exponent as 1/10^3.

Step-by-step explanation:

The expression 10^(-3) can be written using a positive exponent as 1/10^3.

To understand this, let's break it down:

10^(-3) means 10 raised to the power of -3.

A positive exponent means we move the decimal point to the right, while a negative exponent means we move the decimal point to the left.

So, if we have 10^(-3), we move the decimal point three places to the left, resulting in 0.001.

Therefore, 10^(-3) can be written as 1/10^3, which is equal to 0.001.
