Question

1.15x10^-7 / 2.5x10^-3 4.6x10^-10 0.46x10^-3 4.6x10^-3 0.46x10^-4

Answer 1

Answer:

The answer to your question is: d) 0.46x10^-4

Step-by-step explanation:

                                        (1.15x10⁻⁷) / (2.5x10⁻³)

First, divide 1.15 by 2.5        1.15 / 2.5 = 0.46

Second, subtract the power    -7 - (-3) = -7 + 3 = -4

Finally, express the number     0.46 x 10⁻⁴

a) 4.6x10^-10

b) 0.46x10^-3

c) 4.6x10^-3

d) 0.46x10^-4
