What is a way to wright 100,000 using exponents
Oxana [17]
We have to wright 100,000 using exponents. The exponent of number shows how many times you use the number in multiplication.
For example: 64 = 8², because: 64 = 8 · 8or: 64 = 4³, because 64 = 4 · 4 · 4  In this case:100,000 = 10 · 10 · 10 · 10 · 10Therefore:100,000 = 10^5 ( or "10 to the fifth power" )Answer: 10^5.
