Question

rewrite using scientific notation 0.0054?

Answer 1

Place a decimal point between the first two nonzero digits 5 and 4 to get

5.4

then you move the decimal 3 spots to the left to get back to 0.0054

So that is why

\[\Large 0.0054 = 5.4 \times 10^{-3}\]

notice the base of 5.4 and the exponent of -3 (the negative 3 tells you to move the decimal point 3 spots to the left)

Answer 2
