What is a way to write 100,000 using exponents?
Helen [10]
ANSWER

100,000=10^5
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

100,000=10 \times 10 \times 10 \times 10 \times 10

Since 10 multiplies itself 5 times to give 100,000, we write

100,000=10^5
