They are all in scientific notation. I'm not sure what your're supposed to do with them, but if you're supposed to change them to regular numbers, just move the decimal point the number of spaces indicated by the power of 10. For example, 21 x 10 to the 2nd power would be 2100. The decimal point moved 2 places to the right. Another way to look at it is that 10 to the 2nd power is 100, you're multiplying 21 by 100.

According to your notes, it's hard to get the answer. It's either
(21x10)x(21x10)
or
21x(10x10)

Look closely at the problem and y ou will see where the multiplication takes place. Figure all the exponents first, then the parts in the parenthesis.

OK..I'll help you with two but you do the rest....
21 x 10 to the 2nd power = (21 x 10) x (21 x 10) = ?

268 x 10 to the 3rd power = (268 x 10) x (268 x 10) x (268 x 10)=?

Get the picture?

Oh my God. You can't calculate this without asking everybody on the Internet to show them how to do it?
