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
4) n=12 this is because 45/4=11.25 and dividing 135 by 11.25 equals to 12
5) n=2.5 this is because 5/2=2.5 and multiplying 1 by 2.5 equals to 2.5
hope this helps :)
