Question

how long could the sun continue producing energy at this rate? remember, it has about 8.8 × 10^56 hydrogen atoms. which scientist do you agree with? (3.7 × 10^38) ÷ (8.8 × 10^56) 4.2045455e - 19 (8.8 × 10^56) ÷ (3.7 × 10^38) 2.378378378e + 18 8.8 × 10^56 ÷ 3.7 × 10^38 2.378378378e + 94

Explanation:

Step1: Recall division rule for scientific - notation

When dividing numbers in scientific notation $a\times10^{m}$ by $b\times10^{n}$, the formula is $\frac{a\times10^{m}}{b\times10^{n}}=\frac{a}{b}\times10^{m - n}$.

Step2: Calculate $\frac{8.8}{3.7}$ and $56-38$

$\frac{8.8}{3.7}\approx2.3784$ and $56 - 38=18$.

Step3: Write the result in scientific - notation

The result of $(8.8\times10^{56})\div(3.7\times10^{38})$ is $2.3784\times10^{18}$.

Answer:

$2.3784\times10^{18}$
