Answer:

see below

Explanation:

1) Use Negative Power Rule:
x^(-a) =(1)/(x^(a) ).


3.4x*(1)/(10^(15) ) +8.1*x*10^(-14)

2) Use Negative Power Rule:
x^(-a) =(1)/(x^(a) ).


3.4x*(1)/(10^(15) ) +8.1*x*(1)/(10^(14) )

3) Use this rule:
(a)/(b) *(c)/(d) =(ac)/(bd) .


(3.4x*1)/(10^(15) )+8.1*x*(1)/(10^(14) )

4) Simplify
3.4x*1 to
(3.4)x.


(3.4x)/(10^(15) ) +8.1*x*(1)/(10^(14) ) }

5) Use this rule:
(a)/(b) *(c)/(d) =(ac)/(bd) .


(3.4x)/(10^(15) ) +(8.1*x*1)/(10^(14) )

6) Simplify
8.1*x*1 to
8.1(x).


(3.4x)/(10^(15) ) *(8.1*x)/(10^(14) )
