Answer 2

to write a number in scientific notation the formula is a * 10^b

a = number other than 0

b = no. of zeroes + no. of digits after decimal point.

49000 + 81000 = 130000=1.3 * 10000

no of zeroes = 4

no. of digits after decimal point = 1

4 + 1= 5 = b

1.3 = number = a

the number in scientific notation is 1.3 * $10^5$
