This is scientific notation.
Scientific notation is straightforward and in this case, the 1 is the base number and the 107 is the number of decimal places (here it would be zeros) following. So, 1 x 107 is 10,000,000. This is generally true for base numbers not showing a decimal point. Just add the number of zeros in the superscript.
The only tricky part to scientific notation has to do with the decimal point.
Consider 3.14 x 105. Clearly 3.14 is the base. If not for the existing decimal point in the base, the 105 would call for 5 zeros at the end, but this is incorrect. (In other words, 3.1400000 is not right!)
Instead, what you need to do is move the decimal point 5 places to the right and add zeros as necessary. The correct answer would be 3.14 x 105 = 314,000.
(To verify, count the number of positions the decimal moved. Recall, any number that does not show a decimal always has an invisible decimal at the end .)

Your 106 is 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000 If you have 10 to a given power, then it's 10 times itself that many times. The rule of thumb is that 10 to any power is a 1 followed by that many zeros. What that means is that if you have 103 you'll have a 1 followed by 3 zeros, or 1,000. In the case of 108 you'll have a 1 followed by 8 zeros, or 100,000,000.
5-7 = 1/57 = 1/78125 = 0.0000128
10 to the power 0 is 1
When we raise a number to a negative exponent, it is the same as taking the reciprocal of the number raised to the positive exponent. So, 10 to the power of -1 is the same as 1 divided by 10 to the power of 1. Since 10 to the power of 1 is 10, the reciprocal of 10 is 1 divided by 10, which equals 0.1 or 1/10.

In the range of 1 x 10^7 1/ohm-m . That's one times ten to the seventh power.
3.45 x 10^1
It is 1, since 1 to any power is 1.
The product of 3.25 times 10 to the 3rd power x 6.1 times 10 to the negative 1 power, expressed in scientific notation, is: 3.25061 × 103
1 times 10 to the power of negative 3 (1 x 10-3)
1 bel represents a power ratio of 10:1. This means that if you have a power input of 1 bel, the output power is 10 times greater.
10 to the 1 power times fourty nine point thirty two = 10
10 to the power of -1 = 0.1 6.3 x 0.1 = 0.63
By definition of powers, x to the power y = x*x*x*........y times x to the power 1 = x Therefore, 10 to the power 1 = 10.
