GMAT Data Sufficiency (DS) | Re: Is x > 10^10 ? (1) x > 2^34 (2) x = 2^35

My working is just a tad different.

Statement 2, enough
Statement 1,
x > 10^10
x > 2^10.5^10

So x > 2^34
x > 2^10.2^24

Now, my thinking was 5 is 2.5 times more than 2, so 5^10 will be closer to 2^20 but w/o working i cant say higher or lower , whereas 2^21 > 5^10 (definite as its 1 more than double), we have 2^24. So sufficient.
I know its not perfect but saved time for me, of course Bunuel's method is flawless !!.
