For this case we have an expression of the form:
[tex]a * e (b)
[/tex]
We can rewrite this expression in scientific notation as:
[tex]a * 10 ^ b
[/tex]
Where,
a: coefficient of scientific notation
b: base ten exponent
We then have the following expression:
[tex]1.8e10
[/tex]
Rewriting we have:
[tex]1.8 * 10 ^ {10}
[/tex]
Answer:
[tex]1.8e10 = 1.8 * 10 ^ {10}[/tex]
