0.1+ 3.93 + 2.9 please do it step by step like which one is first second third. thank you so much !

6.93

Step-by-step explanation:

0.1+3.93=4.03

4.03+2.9=6.93

the answer is 6.93

the answer is 108

Step-by-step explanation:

a x 10b

Follow the steps below to see how 100,000,000 is written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 100,000,000

New Number: 1.00000000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number:1.00000000

Decimal Count:  12345678

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1 x 108

Step 4

Check your work:

108 = 100,000,000 x 1 = 100,000,000
