1. The coefficient (green) is 45
2. The exponent (yellow) is 9
<h3>Conversion scale</h3>
To convert from giga grams (Gg) to grams (g), the following coversion scale can be use:
1 Gg = 10⁹ g
With the above convesion scale, we can convert 45 Gg to g as follow
1 Gg = 10⁹ g
Therefore,
45 Gg = 45×10⁹ g
Thus, 45 Gg is equivalent to 45×10⁹ g. Hence, we can conclude as follow:
- The coefficient (green) is 45
- The exponent (yellow) is 9

I believe the answer is A (it was on another Brainly question as well).
Is an example of a climate change
Answer:
Explanation:
a )
m = m₀ 
m is mass after time t . original mass is m₀ , λ is disintegration constant
λ = .693 / half life
= .693 / 1590
= .0004358
m = m₀ 
b )
m = 50 x 
= 40.21 mg .
c )
40 = 50 
.8 =
= 1.25
.0004358 t = .22314
t = 512 years .
