The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct.
What is summation?
A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.
Given the digits are
2.54 x 10¹⁹ and 3.218 x 10¹⁷
Now in order to sum we need to make an equal exponent of 10
So,
2.54 x 10¹⁹ = 254 x 10¹⁷
Now, Summation
254 x 10¹⁷ + 3.218 x 10¹⁷
257.218 x 10¹⁷ = 2.57218 x 10¹⁹
Hence "The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct".
