b. multiply the exponents of the 10 together
c. subtract the exponents of the 10 from the other
d. divide the exponents of the 10 by the other

Respuesta :

apologiabiology
you add the exponents
remember
[tex](x^m)(x^n)=x^{m+n}[/tex]

so

2 numbers in scientific notation are
[tex](a*10^m)(b*10^n)=(a)(10^m)(b)(10^n)=(ab)(10^m*10^n)=(ab)(10^{m+n})[/tex]


so add them
