Answer 1

Note: In the given expression, it must be $10^4$ instead of $19^4$.

Given:

The expression is:

$(6.31\times 10^5)+(2.6\times 10^4)$

To find:

The value of the given expression.

Solution:

We have,

$(6.31\times 10^5)+(2.6\times 10^4)$

On simplification, we get

$=6.31\times 100000+2.6\times 10000$

$=631000+26000$

$=657000$

$=6.57\times 100000$

$=6.57\times 10^5$

Therefore, the value of the given expression in scientific notation is $6.57\times 10^5$.
