Options:
a) 40
b) 4 × 10^(-5)
c) 4 × 10^(0)
d) 40,000

Answer 1

c) 40 x 10^{0} or simply 40

Step-by-step explanation:

To find the product of 8 x 10^{-3} x 5 x10^{3}, you multiply the numerical parts and add the exponents:

8 x 10^{-3} x (5 x 10^{3} = (8 x 5) x 10^{(-3 + 3)

= 40 x 10^{0}

So, the answer is:

c) 40 x 10^{0} or simply 40
