1) 2
2) 1.15741 x 10^-5
3) 27,000,000
4) 8.9987 x 10^7
5) 2.3 x 10^-8; 3.2 x 10^-10; 2.3 x 10^-10; 2.3 x 10^-12
6)4.39814 x 10^2 days
7) 2.62 x 10^6
8) 9.3
9) 4.79 x 10^-3
10) 1.98 x 10^-3
11) 6.08 x 10^12
12) 1.2 x 10^4
13) 4.3 x 10^3
14) 3 x 10^-3
15) The coefficient, 1.78, is a number between one and ten. The power of 10, and 12, shows how far to the right the decimal point must be pushed to achieve the actual amount.
it can be written as 1.78 × 10^12
This means Charlee's product is a big number, equal to 1.78 multiplied by 10 raised to the power of 12.
we can show it as 1.78 × 1,000,000,000,000
the number Charlee was calculating is 1.78 trillion.
15 is a short answer and I just finished the test so I don't know if I'm right.
