Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1
_____
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
_____
Of course, it can be useful to understand how moving the decimal point changes the exponent:
9 = 0.9×10 = 0.9×10^1
