Answer:
3.3 x 10⁻⁴
Step-by-step explanation:
Given expression:

To solve this problem;
10° = 1
So;

=
x 10⁻³
= 0.33 x 10⁻³
= 3.3 x 10⁻¹ x 10⁻³
= 3.3 x 10⁻⁴

Answer:
a²/9
Step-by-step explanation:
(27a⁻³) (-⅔) = 27^(-⅔) × (a⁻³)^(-⅔)
= (3³)^(-⅔) × a²
= 3⁻²a²
= a²/9
To answer this question you have to determine how many feet are in a mile and multiply it by 70. There are 5280 feet in a mile, so 5280 x 70= 369600. So he can run 369600ft in an hour. (im pretty sure lol, i feel like i may have misunderstood this question, are there any answer choices?)
