10-7 is the same as 1/107, or 0.000 000 1
So 3*10-7 = 0.000 000 3
In words, 10-7 is one in ten million. So you are talking about three in ten million.
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.
10-3 is equivalent to 0.001.
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
3 times 10 to the 8th power divided by 7 times 10 to the negative 7th power equates to: 4.28571428571

3.27*10-3=.00327
10 to the power 3 means 10*10*10, or 1000 10 to the power MINUS 3 means 1 over 10 to the power 3, so 1/1000.

To add (5.8 \times 10^{-3}) and (1.6 \times 10^{-6}), we first convert (1.6 \times 10^{-6}) to the same exponent as the first term. This becomes (0.0000016), or in scientific notation, (0.0000016 = 0.0000058) when expressed with the same exponent. Therefore, (5.8 \times 10^{-3} + 0.0000016) is approximately (5.8000016 \times 10^{-3}), which can be written as (5.8 \times 10^{-3}) when rounded to three significant figures.
10-3 is equivalent to 0.001.
(-6) x (-3) = 18 (-10) x (-9) = 90 18 - 90 = -72
x = 10 Minus 6 times 10 = minus 60 Add 3 to minus 60 = minus 57
4.5 x 10 - 3 = 42

Four times 3^2 minus two = 34.
115 - 102 + (3 x 5) = 30
