Question

What is 6.43 x 10^7 in standard notation?A.643 x 10^5B.64,300,000C.6,430,000,000D.64.3 x 10^10

Answer 1

Step 1

Standard notation of a number is when a number is written with only number digits and not in scientific notation.

E.g 1235679 is in standard notation

1.235679 x 10^6 is in scientific notation

Step 2

Write 6.43 x 10^7 in standard notation

$\begin{gathered} 10^7=\text{ 10000}000 \\ 6.43\text{ x 10000000= 64,300,000} \end{gathered}$

Hence the answer is option B
