all the expressions that are equivalent to 10 to the 9 x 10 to the 3.

10^12

10 * 10^11, 10^2*10^10, 10^4*10^8, 10^5*10^7, 10^6*10^6.

To find all the expressions that are equivalent to \(10^9 \times 10^3\), we can use the rule of exponents which states that when multiplying two numbers with the same base, we add their exponents. In this case, the base is 10.

Using the rule of exponents, we can simplify the expression as follows:

\(10^9 \times 10^3 = 10^{9+3} = 10^{12}\)

So, the expression \(10^9 \times 10^3\) is equivalent to \(10^{12}\).

However, if you're looking for other expressions that are equivalent to \(10^9 \times 10^3\), you can use the commutative property of multiplication to rearrange the order:

\(10^9 \times 10^3 = 10^3 \times 10^9 = 10^{3+9} = 10^{12}\)

This means that \(10^9 \times 10^3\) is also equivalent to \(10^{3+9}\) and \(10^{12}\).

In summary, the expression \(10^9 \times 10^3\) is equivalent to \(10^{12}\), and other equivalent expressions include \(10^{3+9}\) and \(10^{12}\).
