Lerok [7]

The Scientific notation of given numbers are  3400=3.4 \times 10^{-3}, 0.000023=2.3 \times 10^{5}, 4.50, 1,000,000=1 \times 10^{6} and 0.00671=6.71 \times 10^{-3}.

The given numbers are 3400, 0.000023, 4.50, 1,000,000 and 0.00671.

<h3>What is scientific notation? </h3>

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

Now, 3400=3.4 \times 10^{-3}, 0.000023=2.3 \times 10^{5}, 4.50, 1,000,000=1 \times 10^{6} and 0.00671=6.71 \times 10^{-3}.

Therefore, the Scientific notation of given numbers are  3400=3.4 \times 10^{-3}, 0.000023=2.3 \times 10^{5}, 4.50, 1,000,000=1 \times 10^{6} and 0.00671=6.71 \times 10^{-3}.
