If k is a positive integer and n=7,049*10^k, what is the value of k?
1. 7,500<n<75,000
2. 10^4<n<10^5

[scoot]

Ans .

opt1) 7500<n<75,000 . n = 70490. suff
opt2) 1000<n<10000. n= 70490. suff

[800ForSure]

1) Suff, only possible value for n= 70490, so K=1
2) Suff, 10,000<n<100,000, n = 70490, k=1

[rd_eastbay]

Agreed.

[asdada1]

1. 7,500<n<75,000 insuff k = 0 or 1

2. 10^4<n<10^5 suff k = 1

[Swiss_boy]

1. 7,500<n<75,000 insuff k = 0 or 1

2. 10^4<n<10^5 suff k = 1

B

if k =0 n = 7049 - out of the scope of range specified above. So k =0 not possible.

[MikeJung]

D it is.

stem 1

if k=0 then the value of n falls outta range.
