apologiabiology

remember
(x^m)(x^n)=x^(m+n)
and commutaitve property

(3.4 times 10^-14) times (1.8 times 10^28)=
(3.4)(10^-14)(1.8)(10^28)=
(3.4)(1.8)(10^-14)(10^28)=
(6.12)(10^(-14+28))=
(6.12)(10^14)

Answer:

\(6.12*10^{14}\)

Step-by-step explanation:

we know that

\((a*10^{m})*(b*10^{n})=(a*b)*10^{m+n}\)

In this problem we have

\(a*10^{m}=3.4*10^{-14}\)

\(b*10^{n}=1.8*10^{28}\)

therefore

\(3.4*10^{-14} *1.8*10^{28}=(3.4*1.8)*10^{-14+28}=6.12*10^{14}\)
