Identify the product and express it in scientific notation. 4.7 x (6.02 x 10^23)

Anna11 [10]

Answer:

$\large\boxed{4.7\times(6.02\times10^{23})=2.8294\times10^{24}}$

Step-by-step explanation:

The scientific notation:

$a\times10^k\ \text{where}\ 1\leq a$

We have:

$4.7\times(6.02\times10^{23})=(4.7\times6.02)\times10^{23}=28.294\times10^{23}\\\\=2.8294\times10\times10^{23}=2.8294\times10^{24}$
