Question

How do you write 2.14 x 10^-5 in standard form by moving the decimal point?

Answer 1

Answer:

21.4 * 10^(-5)

Answer 2

$\\ \sf\longmapsto 2.14\times 10^{-5}$

• Cancel 1 by 1

$\\ \sf\longmapsto 0.214\times 10^{-4}$

$\\ \sf\longmapsto 0.0214\times 10^{-3}$

$\\ \sf\longmapsto 0.00214\times 10^{-2}$

$\\ \sf\longmapsto 0.000214\times 10^{-1}$

$\\ \sf\longmapsto 0.0000214$
