What are you struggling with? Put it into a calculator then quote the answer to 2 significant figures in standard form.

I tried another similar one on MathsWatch and, despite the correct answer, didn't satisfy MathsWatch! Will try to investigate this later, when I get a moment.....

LOL! Working out! Reckon you just typed it into a calculator and then rounded it! Very difficult to get the precise answer that MathsWatch thinks is right, with these!
