1.4×1011

Explanation:

(3.5×10×10×10×10×10×10)×(4×10×10×10×10)

When a×a, it can also be written as a2, hence, apply this to the equation and we get,

(3.5×106)×(4×104)

Remove parenthesis,

3.5×106×4×104

Move like-terms together,

3.5×4×106×104

Simplify,

14×1010

Since 14>10, divide 10 from 14,

1.4×10×1010

Refine,

1.4×1011
