question
what is the product of 6.8 × 10^4 and 9.3 × 10^6 expressed in scientific notation?
answer attempt 1 out of 3
answer: × 10^

Explanation:

Step1: Multiply the coefficients

$6.8\times9.3 = 63.24$

Step2: Add the exponents of 10

$10^{4}\times10^{6}=10^{4 + 6}=10^{10}$

Step3: Rewrite in scientific - notation

$63.24\times10^{10}=6.324\times10^{11}$ (since $63.24 = 6.324\times10^{1}$ and when multiplying by $10^{10}$, we add the exponents $1 + 10=11$)

Answer:

$6.324\times10^{11}$
