Answer:

#1.213 xx 10^1 + 1.5 xx10^0#

Explanation:

You would not really want to use scientific notation in this case - it is intended for very large or very small numbers.

But anyway, here it is:

#1.213 xx 10^1 + 1.5 xx10^0" "larr# the powers of 10 are different.

If you do want to add them, the powers must be the same:

#=1.213 xx 10^1 +0.15 xx 10^1" "larr# now you can add them:

#=1.363 xx 10^1#
