See the entire solution process below:

First, rewrite this as:

#13.7 xx 10^1 + 4.142 xx 10^1 =#

#(13.7 + 4.142) xx 10^1 =#

#17.842 xx 10^1 =#

#1.7842 xx 10^2#

or

#178.42#

#1.37×10^2+4.142×10^1=1.7842×10^2#

#1.37×10^2+4.142×10^1#

= #13.7×10^1+4.142×10^1#

= #(13.7+4.142)×10^1#

= #17.842×10^1#

= #1.7842×10^2#
