(6.31 x 10^5) + (2.6 x 10^4)
First, you solve the exponents by raising the bases to their powers.
10^5 = 10 x 10 x 10 x 10 x 10
10^5 = 100,000
Then, you multiply 100000 by 6.31 to get 631,000.
Our left side is 631,000.
Next, you solve the exponents to the right side.
10^4= 10 x 10 x 10 x 10
10^4 = 10,000
2.6 x 10000 = 26,000
Lastly, we have to add them together.
631,000 + 26,000 = 657,000
