Is 21.8 x 10 to the power of 8 a scientific notation

Oksanka [162]

Answer:

$\large\boxed{2.128\times10^9}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k\\\\1\leq a$

We have:

$21.8\times10^8$

21.8 >10

21.8 = 2.18 × 10

Thereofre:

$21.8\times10^8=2.18\times10\times10^8$

Use

$a^n\cdot a^m=a^{n+m}$

$21.8\times10^8=2.18\times10^1\times10^8=2.18\times10^{1+8}=2.18\times10^9$
