To multiply the two numbers in scientific notation, you can multiply the coefficients and add the exponents.
Given:
\[
(4 \times 10^{26}) \times (3.15 \times 10^{7})
\]
1. **Multiply the coefficients**:
\[
4 \times 3.15 = 12.6
\]
2. **Add the exponents**:
\[
26 + 7 = 33
\]
So, we have:
\[
12.6 \times 10^{33}
\]
Next, we need to express \(12.6\) in proper scientific notation. We can write \(12.6\) as \(1.26 \times 10^{1}\). Therefore, we can rewrite:
\[
12.6 \times 10^{33} = 1.26 \times 10^{1} \times 10^{33}
\]
When you combine the exponents:
\[
1.26 \times 10^{34}
\]
Thus, the final result in scientific notation is:
\[
1.26 \times 10^{34}
\]

The product of \( (4 \times 10^{26}) \times (3.15 \times 10^{7}) \) calculated as \( 1.26 \times 10^{34} \) can be expressed as a decimal by expanding the scientific notation.
To convert \( 1.26 \times 10^{34} \) into decimal form:
1. Start with \( 1.26 \).
2. Move the decimal point 34 places to the right.
This gives:
- Move the decimal point 2 places to get \( 126 \).
- Now you have \( 126 \), and you'll still need to move it 32 more places to the right.
By adding 32 zeros after 126, the result is:
\[
1260000000000000000000000000000000
\]
Thus, \( 1.26 \times 10^{34} \) in exact decimal form is:
\[
1260000000000000000000000000000000
\]
