Respuesta :

Solution for question 1:

[tex]\frac{4 * 10^15}{8 * 10^9}[/tex]

Put it in this format:

[tex]\frac{2^2 * 10^15}{2^3 * 10^9}[/tex]

Solving;

2(²-³) × 10^(15-9)

2^-1 × 10^6 = 1/2 × 10^6

That gives 5 × 10^5


Solution to question 2:

[tex]\frac{2^1 * 10^-5}{2^2 * 10^-12}[/tex]

Solving;

2^(1 - 2) × 10^(-5 + 12)

= 1/2 × 10^7

That gives;

5 × 10^6
