Question

What is the sum of 3.6×10^3 And 6.1×10^3

Answer 1

3.6(103)+6.1(103)=9700

Answer 2

these are scientific notations

first:

`\\ 3.6 * {10}^(3) = 3600 \\ \\ 6.1 * {10}^(3) = 6100`
so :

`6100 + 3600 = 9700`
now you can change it back to scientific notations

`9700 = 9.7 * {10}^(3)`

or you can do that in an easier way: (this situation goes only if the powers of 10s are equal)


`3.6 * {10}^(3) + 6.1 * {10}^(3) = 9.7 * {10}^(3)`

good luck
