ANSWER
[tex]100,000=10^5[/tex]
EXPLANATION
We want to write 100,000 using exponents.
This means that, we want to write 100,000 as an index number, that is a certain number raised to a certain index or exponent.
The exponent tells us how many times that number multiplies itself to give 100,000
[tex]100,000=10 \times 10 \times 10 \times 10 \times 10[/tex]
Since 10 multiplies itself 5 times to give 100,000, we write
[tex]100,000=10^5[/tex]
