Which conversions from scientific notation to standard notation are true? check all that apply.

The correct conversion from scientific notation to standard notation are:

            b)  

            e)  

We know that when we have  a power of 10 as positive then the decimal is shifted to the right and if the power of 10 is negative then we shift the decimal to the left.

a)

As the power of 10 is positive hence we shift the decimal to the right 3 places.

Hence, the conversion is:

b)

Again the power of 10 is positive and hence we will shift the decimal 5 places to the right and the conversion is done as follows:

c)

Since, the power of 10 is positive and hence we will shift the decimal 4 places to the right and we convert the number to standard notation as:

d)

Since, the power of 10 is negative and hence we will shift the decimal 3 places to the left and we convert the number to standard notation as:

e)

Since, the power of 10 is negative and hence we will shift the decimal 8 places to the left.

Hence, we convert our number to standard notation:

i think it is 18
