Answer:
a.[tex]3.43\times 10^6[/tex]
b.[tex]4.532\times 10^{-3}[/tex]
Step-by-step explanation:
The scientific notation is when numbers are written in the form;
[tex]k\times 10^n[/tex], where n is an integer and [tex]1\le k\:<\:10[/tex].
The given number is : 3,430,000
The decimal point is currently after the last digit: 3,430,000.0
We move it back until we get k=3.43 and n=6.
The scientific notation is:
[tex]3.43\times 10^6[/tex]
b. The second number is 0.004532
We can clearly see the decimal point this time.
We move forward until we get k=4.532 and n=-3
The scientific notation is:
[tex]4.532\times 10^{-3}[/tex]
