#1.4xx10^11#

Explanation:

#(3.5xx10xx10xx10xx10xx10xx10)xx(4xx10xx-10xx10xx-10)#

When #axxa#, it can also be written as #a^2#, hence, apply this to the equation and we get,

#(3.5xx10^6)xx(4xx10^4)#

Remove parenthesis,

#3.5xx10^6xx4xx10^4#

Move like-terms together,

#3.5xx4xx10^6xx10^4#

Simplify,

#14xx10^10#

Since #14>10#, divide #10# from #14#,

#1.4xx10xx10^10#

Refine,

#1.4xx10^11#
