Question 601727
Simplify and write your answer to one significant digit:
(0.0086 X 10 (to the negative two power) ) (1.2 X 10 (to the eight power) )
0.0086E-2
= 8.6E-5
----------
8.6E-5 * 1.2E10 = 8.6*1.2E5
= 10.32E5
= 1.032E6
To 1 digit = 1E6
or {{{1.0*10^6}}}
----------

(2 X 10 (to the eight power) ) (60,000)
2E8*6E4 = 12E12
= 1.2E13
--> 1E13
or {{{1*10^13}}}
-----------------
Do the others the same way.
& 
(40 X 10 (to the negatvie tenth power))(42 X 10 (to the negative fourth power) )

(97, 400) (425) 
I don't know what that means.
