(4*10^1)^ -5
PEMDAS
ten to the first power if ten so, (4*10)^ -5
4* 10 is forty and since it is raised to the negative fifth power your have to put it under one to make it positive
so it becomes fraction form of... 1/40^5
you raise 40 to the fifth making it, 102,400,000 and then end answer is
1/102,400,000
