calculista

we have

[tex](3.8*10^{8})*(6.9*10^{5})[/tex]

Combine like terms

[tex](3.8*10^{8})*(6.9*10^{5})=(3.8*6.9)*(10^{8}*10^{5})[/tex]

Multiply

[tex]=(26.22)*(10^{8+5})[/tex]

[tex]=(26.22)*(10^{13})[/tex]

[tex]=(2.622*10)*(10^{13})[/tex]

[tex]=(2.622)*(10^{13+1})[/tex]

[tex]=(2.622)*(10^{14})[/tex]

therefore

the answer is the option B

[tex](2.622)*(10^{14})[/tex]
