Answer:
It is greater by 2*10^3 times.
Step-by-step explanation:
Given:
Two numbers in scientific form we have to find the differences.
Using exponents product rule.
We know that [tex]a^x\times a^y=a^x^+^y[/tex] base same then exponents are added.
So,
⇒ [tex]4\times 10^-^6\times 2\times 10^3[/tex]
⇒ [tex]8\times 10^-^6^+^3[/tex]...powers are added
⇒ [tex]8\times 10^-^3[/tex]
We see that after multiplication with [tex]2\times 10^3[/tex] the numbers are same.
Then we can say that [tex]8\times 10^-^3[/tex] is [tex]2\times 10^3[/tex] times greater than [tex]4\times10^-^6[/tex]
So 8 x 10^-3 is 2x10^3 times as great as 4 x 10^-6 .
