In this case we have the following expression:
We know that Karen was trying to factor out this and she found that the greatest common factor of these terms was 2, in other words we can write this expression as:
An area model for this expression could be the area of a rectangle that has the following dimensions:
So the area model can be written as:
By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.
Given that,
(2.310⁵)(1.5
10⁴)
By using scientific notation
The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.
Now, we calculate
(2.310⁵)=2.5
100000=230000
(1.5 10⁴)=1.5
10000=15000
Now,
=23000015000
=3450000000
=345 10⁷
Therefore, By using scientific notation we calculated (2.310⁵)(1.5
10⁴) we got 345
10⁷.

Answer:
a = -12
Remember that when a variable is times with a number, you <u>divide</u> the number on both sides.
When a variable is divided by a number, you <u>multiply</u> the number on both sides.
