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

Select all of the expressions equivalent to `-15+6x`.

To find the expressions that are equivalent to 10^9 x 10^3, we need to understand the properties of exponents.

When multiplying two numbers with the same base, we add their exponents.

So, 10^9 x 10^3 can be written as 10^(9+3).

Using this property, we can determine the equivalent expressions:

1. 10^(9+3) -> 10^12
2. 10^(9+3) -> 10^12
3. (10^9) x (10^3) -> 10^(9+3) -> 10^12
4. (10^9) x (10^3) -> 10^(9+3) -> 10^12
5. 10^12

Therefore, the expressions that are equivalent to 10^9 x 10^3 are:
1. 10^12
2. (10^9) x (10^3)
3. 10^(9+3)
4. 10^12
5. (10^9) x (10^3)

To find the expressions that are equivalent to 10^9 x 10^3, we need to know the property of exponents.

The property states that when you multiply two numbers with the same base, you can add their exponents.

So, applying this property to 10^9 x 10^3, we add the exponents 9 and 3:

10^9 x 10^3 = 10^(9 + 3) = 10^12

Now, we can look at the given expressions and select the ones that are equivalent to 10^12:

1. 10^(9 + 3)
This expression is equivalent to 10^12, as we just calculated.

2. (10^9)(10^3)
Using the property stated above, we add the exponents: 10^(9 + 3) = 10^12.
Therefore, this expression is also equivalent to 10^12.

3. 10^(9 x 3)
This expression is not equivalent. 9 x 3 is 27, so this expression is equal to 10^27, not 10^12.

4. 10^12
This is already in the form 10^12, which means it is equivalent to 10^12.

So, the expressions that are equivalent to 10^9 x 10^3 are:

- 10^(9 + 3)
- (10^9)(10^3)
- 10^12

Hi yesennia,

Please include all the expressions in your question. No one will be able to answer if we aren't given the answer choices!
