2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2x2 ? was never very good at "the math" though
I think it's 2 with a little 50 about the top right hand ie. two to the power 3 is 2³ and 2 to the power of 30 is 2³º
Why have you got to do homework? Surely it's your kids to do - just point them in the direction of where they can find the answer, thats how you should help, it also avoids you looking like you don't know!
2 with a small 50 at the top right hand side or 2x2 etc http://www.bbc.co.uk/schools/gcsebitesize/maths/numberih/powersrev2.shtml
I agree <font size="5"> 2 to the power of 50 = 2<sup>50</sup> </font><font size="5">= 1125899906842624 </font><font size="5">˜</font><font size="5"> 1.12589991 × 10<sup>15</sup> </font><font size="5"> Also equal to: 2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2x</font><font size="5">2x2x2x2x2</font> <font size="5"><sup> </sup></font>
