Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
The answer is 9x10 to the positive 16 power
The sum of the given equation in the scientific notation should be [tex]9 \times 10^{16}[/tex]
Here we Move the decimal due to this there is one non-zero digit to the left of the decimal point. In the case when the decimal is being moved to the right, so the exponent will be negative and vice versa.
So,
[tex]= (2 \times 10^{16}) + (7 \times 10^{16}) = 9 \times 10^{16}[/tex]
