Answer 1

Answer:

The answer to your question is below

Step-by-step explanation:

When using scientific notation,

- when we move the decimal point to the right, the power will be negative.

- when we move the decimal point to the left, the power will be positive.

a) 0.00001    move the decimal point 5 places to the right   1 x 10⁻⁵

b) 0.001         move the decimal point 3 places to the right   1 x 10⁻³

Answer 2

Answer:

• 10^-5
• 10^-3

Step-by-step explanation:

You know from place values that ...

  0.00001 = 1/100,000 = 1/10^5 = 10^-5

and

  0.001 = 1/1000 = 1/10^3 = 10^-3

_____

The applicable rule of exponents is ...

  1/a^b = a^-b
