Can someone explain this math problem to me? so, (7.14 x 10^10) + (3.21 x 10^10) equals 1.035 x 10^11, but what i'm stuck on, is how does 10^10 end up being 10^11?

Given problem is:

step by step solution:

we will add similar elements.

=

Now converting in decimal form we get 10000000000 (10 zeroes)

Now multiplying 10.35 with 10000000000 we get 103500000000 (8 zeroes)

or we can change it to exponential form like

11 because when you count from the extreme right end '0' and come counting to the left side, you skip 11 numbers till you reach the first number '1'. And when you put a decimal after 1st number, so the last '0' is at the 11th place, that is why it is .

i think that you should ask google for the answer to that problem because if we don't know it google does
