Question

ayuda !!!! potecias 937 X 10^13 +4.7X10^15=


b) 6.1X10^-2 - 3x10^-1=

c) 33x10^4 - 27x10^5=

Answer 1

Explicacion
a)
937 exp +13  +  4.7 exp +15 = 93700 exp +15  +  4.7 exp +15
(93700  +  4.7) exp +15  = 93704.7 exp +15
b)
6 exp -2  - 3 exp-1 = 6 exp-2  - 0.3 exp-2 = (6  -  0.3) exp -2
(6  -  0.3) exp -2 = 5.7 exp -2
c)
33 exp +4    -    27 exp +5 = 330 exp +5  -  27 exp +5 = (330 - 27) exp +5
(330 - 27) exp +5 = 303 exp +5
