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