POTENCIAS DE 10.

POSITIVAS:

10^0 = 1

10^1 = 10

10^2 = 100

10^3 = 1000

10^4 = 10000

NEGATIVAS:

10^-1 = 0.1

10^-2 = 0.01

10^-3 = 0.001

10^-4 = 0.0001

10^-5 = 0.00001

SUMA:

3x10^8 + 25000x10^4 = 3x10^8 + 2.5x10^8 = 5.5x10^8

0.0000251x10^-19 + 351x10^-19 = 25.1x10^-19 + 351x10^-19 = 376.1x10^-19 = 3.76x10-17

RESTA:

75x10^8 - 3.5x10^8 = 71.5x10^8 = 7.15x10^9

MULTIPLICACIÓN: Se suman los exponentes.

(0.2x10^-10)(7x10^-15) = 1.4x10^-25

(751x10^-20)(3x10^-7) = 2253x10^-13 = 2.253x10^-10

DIVISIÓN: Se restan los exponentes.

3x10^8/0.5x10^2 = 6x10^6

251x10^8/35x10^-3 = 7.1714x10^11
