Answer:
[tex]2\cdot 10^3[/tex]
Step-by-step explanation:
We have given an expression 20*100 which will be equal to 2000
And since, we have to write it in the powers of 10 we will put all zeroes in power of 10
Like here, we have total 3 zeroes then we will write it as
[tex2\cdot 10^3[/tex]
Whenever we need to write the expression in term of power of 10 we will always consider all the zeroes in power of 10
If it would have been 200000 then we will write it as
[tex]2\cdot 10^5[/tex]
