- Then we multiply this number with an exponent of 10.
Hence, any number in scientific notation is in the form 
Here a is any number between 1 and 10.
b is exponent of 10.
Now, writing 500 in scientific notation, we take a = 5
Hence, we have to take b = 2, since 5 multiplied by 100 equas 500.
Thus, we have

Answer:

Step-by-step explanation:
So what we should do is first expand. What I did was I did it one step at a time, starting with (2x+5)(2x+5). This gave me
. I then continued to do this, until I got
. Then you asked me what this would be subtracted from 1. So, what I did was set it so that it would follow this rule, making it
.
After this, I just simplified.
