10^68
Technically in your initial problem "squaring" is the wrong term. Squaring is when you take a number such as 10 and bring it to the 2nd power.
That would be 10^2 which is 10*10 which is 100.
As for the correct term. You could say the phrase, "10 brought to the power of 68."
10^68
1. 10 * 10 = 100
2. 100 * 10 = 1,000
3. 1000 * 10 = 10,000
4. 10,000 * 10 = 100,000
5. 100,000 * 10 = 1,000,000
6. 1,000,000 * 10 = 10,000,000
7. 10,000,000 * 10 = 100,000,000
8. 100,000,000 * 10 = 1,000,000,000
9. 1,000,000,000 * 10 = 10,000,000,000
10. 10,000,000,000 * 10 = 100,000,000,000
And it keeps going higher and higher gaining a 0 each time.
So what we can do to speed up the process is:
Our original number:
10 can be written as:
1.0x10
When you add a zero each time the power of 10 will go up by 1. Currently it is at a power of 1. So if you wanted to get to 68 you'd need this:
1.0x10^68
Which would be this:
100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
