Answer to Problem 3GP

The solution of the expression in scientific notation is $7.982033\times {10}^7$

Explanation of Solution

Given information :

The expression is $\left(2.003\times {10}^4\right)+\left(7.98\times {10}^7\right)$

Calculation :

The value of the expression is:

  $\begin{array}{l}\left(2.003\times {10}^4\right)+\left(7.98\times {10}^7\right)\\ \left(2.003\times {10}^4\right)+\left(7980.0\times {10}^4\right)\\ \left(2.003+7980.0\right)\times {10}^4\\ 7982.003\times {10}^4\\ 7.982033\times {10}^7\end{array}$

Hence, the solution of the expression in scientific notation is $7.982033\times {10}^7$
