Answer 2

It seems like you're performing some mathematical operations with numbers in scientific notation. Let's calculate the results:

1. $1.29 \times 10^{11} - 1.37 \times 10^{11}$

To subtract these numbers, you need to have the same exponent (power of 10). In this case, they both have $10^{11}$, so you can directly subtract the coefficients:

$1.29 \times 10^{11} - 1.37 \times 10^{11} = (1.29 - 1.37) \times 10^{11} = -0.08 \times 10^{11} = -8 \times 10^{9}$.

2. $1.29 \times 10^{11} - 1.26 \times 10^{11}$

Again, both numbers have the same exponent ($10^{11}$), so you can subtract the coefficients:

$1.29 \times 10^{11} - 1.26 \times 10^{11} = (1.29 - 1.26) \times 10^{11} = 0.03 \times 10^{11} = 3 \times 10^{9}$.

3. $1.29 \times 10^{11} - 1.24 \times 10^{11}$

Once more, both numbers have the same exponent ($10^{11}$), so you can subtract the coefficients:

$1.29 \times 10^{11} - 1.24 \times 10^{11} = (1.29 - 1.24) \times 10^{11} = 0.05 \times 10^{11} = 5 \times 10^{9}$.

So, the results are as follows:

1. $1.29 \times 10^{11} - 1.37 \times 10^{11} = -8 \times 10^{9}$.
2. $1.29 \times 10^{11} - 1.26 \times 10^{11} = 3 \times 10^{9}$.
3. $1.29 \times 10^{11} - 1.24 \times 10^{11} = 5 \times 10^{9}$.
