that x should be replaced with * or ×. Wasted my 1 minute for this question -_- ..........................................................................................................................

Solution!

Consider 100,000,000 × 100,000,000 = 10^8 * 10^8 and the answer is 1e+16 meaning 10^16

Options are

*blah blah blah... e+30 *blah blah blah... e+16 *blah blah blah... e+27 *blah blah blah... e+98 So definitely it is in range of e+16.

BUT STILL THERE IS THIS LOGIC! hope it helps Aayush Patni!

Cheers (:
