Maggie, Brian, and Joe are solving a division problem with scientific notation.
Maggie
6.89⁻⁴/7.5 x⁻⁶ = .92 x⁻¹⁰
=9.2 x⁻¹¹

Brian
6.89⁻⁴/7.5 x⁻⁶ = .92 x⁻¹⁰
=9.2 x⁻⁹

Joe
6.89⁻⁴/7.5 x⁻⁶ = .92 x²
=9.2 x³

Explain in detail using words the step by step process that Maggie took to solve the problem. Is Maggie correct? If not, where did she go wrong
