Answer:
1
Explanation:
concepts used is law of indices
where
(a^b)^c = a^bc
a^m/a^n = a^(m-n)
a^m *a^n = a^(m+n)
a^0 = 1

50000)^2 = (5*10^4)^2 = 25*10^8
(0.00002)^3 = (2*10^-5)^3 = 8*10^-15
(0.0000001) = 10^-7
now
(50000)^2×(0.00002)^3\(200)×(0.0000001) = 25*10^8 * 8*10^-15/200*10^-7
= 200*10^8-15-(-7)/200 = 10^-7 +7 = 10^0 = 1
Thus,1 is the answer
