Hint: to multiply a decimal amount by 10, all you do is move the point one place to the right...
0.7 x 10 = 7
10000
10^4 is 10 multiplied by itself four times: 10 x 10 x 10 x 10 = 10,000 x 1 = 10,000
-2
y = 10 y = log x (the base of the log is 10, common logarithm) 10 = log x so that, 10^10 = x 10,000,000,000 = x
x-10=15 Add 10 to both sides x=25

4.08 x 10 to the 12th power is 4.08 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 which is 40.8 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 which is 408 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 which is 4080000000000
10 x 10 x 10 x 10 x 10 x 10 = 1,000,000
Exponents (sometimes called powers or indices - the plural of index) are a simple and easy notation, and they save a lot of time. For exampe, say you wanted to write out a googol in full; that is, 10100. * Which is easier to do: that exponent, or 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10? * Another example is the opposite: 10-60, or 0.0000000000000000000000000000000000000000000000000000000000001? So exponents make life very easy for mathematicians, physicists, chemists, engineers and many other people that have to deal with large numbers on a regular basis. Another effect of using exponents is that multiplication is also easier. For 211 x 218, rather than work out 218 and 211 and then mulitply those large numbers together, we can simply add the exponents and then calculate the final result, i.e. 229 (which for the record, is 536870912). The opposite works for division as well; simply subtract the exponents to get the divided amount. They can be used in many other ways as well to make working very large or very small numbers much easier.
the math for 1021 is 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10 X 10. or in short 10 times itself 21 times. the answer is 10000000000000000000000
10 x 10 x 10 x 10 x10 x 10 x 10 =10,000,000
