Question

(2.3 x 10^3) + (6.9 x 10^3)​

Answer 1

The solution of (2.3 x 10^3) + (6.9 x 10^3)​ is
`9.2 * 10^3` that is 9200

Solution:

Need to solve the following expression:

`\left(2.3 * 10^(3)\right)+\left(6.9 * 10^(3)\right)`

There are two terms in given expression

Let’s find GCF for this two terms

The greatest number that is a factor of two (or more) other numbers. When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

`\begin{array}{l}{2.3 * 10^(3)=2.3 * 10^(3)} \\\\ {6.9 * 10^(3)=3 * 2.3 * 10^(3)}\end{array}`

`\text {So GCF between two terms is } 2.3 * 10^(3)`

Let’s bring GCF out of the bracket in expression for sake of simplicity.

`\begin{array}{l}{=>2.3 * 10^(3)(1+3)} \\\\ {=>2.3 * 10^(3) * 4} \\\\ {=>9.2 * 10^(3)} \\\\ {=>9200}\end{array}`

Hence on solving the expression (2.3 x 10^3) + (6.9 x 10^3) the result we get is
`9.2 * 10^3` that is 9200
