Answer: Time taken by computer to solve [tex]3\times10^6[/tex] math problems = 75 seconds
The operation we are here is "Multiplication".
Step-by-step explanation:
Given : Time taken by computer to solve a calculation = [tex]2.5\times10^{-5}[/tex] seconds.
Then, the time taken by computer to solve [tex]3\times10^6[/tex] math problems will be :-
[tex]3\times10^6\times2.5\times10^{-5}\\\\=3\times2.5\times10^6\times10^{-5}\\\\\text{By using exponent rule }a^m\times a^n=a^{m+n}\\\\=7.5\times10^{6-5}\\\\=7.5\times10=75[/tex]
Hence, time taken by computer to solve [tex]3\times10^6[/tex] math problems = 75 seconds
