Write the following numbers in scientific notation: 3,430,000 & 0.004532

a.

b.

Step-by-step explanation:

The scientific notation is when numbers are written in the form;

, where n is an integer and .

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:

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:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
