Question

when a number in scientific notation contains a significant zero, is that zero also significant in the expanded notation? give two examples to support your answer. PLEASE HELP I NEED ANSWERS ASAP

Answer 1

I believe you are referring zero as the exponent. Any number (except 0) with exponent 0 is defined to mean 1.

For one thing, there is a rule: 

 a^m/ a^m = a^m-m = a^0

But (when a is not equal to 0),

a^m/ a^m = 1

Therefore, we must define a^0 as 1.
