What is 5.8x10 to the power of minus 3 plus 1.6 x10 to the power of minus 6?

Answer 1

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.
