The number 65,000 expressed in scientific notation as a number between 1 and 10 times a power of ten is

 [A]. 0.65 × 104 [B]. 6.5 × 104 [C]. 65 × 104 [D]. 650 × 103

Explanation:

No answer description available for this question.

 Mahalakshmi said: (Dec 10, 2010) 65,000 can be written as 65*1000 1000=10^3 65=6.5*10 Therefore 6.5*10^4

 Tejaswini said: (Mar 6, 2011) Look at the options oprionA: 0.65 is not between 1and 10 option B: 6.5 is the number between 1and 10 so 65000 means 6.5*10^4 and remaining options 65 and 650 also not the numbers between 1 and 10 So ans is optionB

 Ragav said: (Oct 1, 2011) I agree with both tejaswani & mahalaxmi.

 Santosh said: (Oct 30, 2011) I agree with mahalaxmi as well as tejaswani.

 Ashish Sharma said: (Oct 12, 2013) 65000 = 65*1000. 65*10^3 = 6.5*10^3+1. = 6.5*10^4.

 Jannat said: (Feb 21, 2014) Why we add +1 here? what is the logical reason behind this?

 Amit Aryan said: (Mar 6, 2014) @Ashish, If u add +1 must divide 10^-1. Like as 6.5*10^3/10^-1.

 Prince Janesh Unique said: (Jul 30, 2014) Here, Without Solvation we can choose Answer cuz the question is asked between the number 1 and 10.. so I seen clearly Option {B} as answer Lets discuss easy manner answer to question. 65,000 = 65*10^3 or 65,000 = 6.5*10^4 is the answer, by decreasing in left side to decimal point, we should add +0 to the right side.

 D.Sudhakar said: (Sep 24, 2014) What means 65* what is the logic in behind this?

 Siva said: (Oct 7, 2014) What is mean by ten?

 Vasanth said: (Oct 8, 2014) But if we do in exponential how can we get this?

 Oladokunibrahim said: (Mar 11, 2015) Am very interested but I did not understand how 1 was added.

 Mostafiz(Eee) said: (Apr 14, 2015) If you normally see, 10*3=3000 (10*10*10) and, 10^3 it is calculation same now, We see 10*10*10*65=65000 ok.

 Shailu said: (Aug 8, 2015) Definitely considered this answer.

 Ajees said: (Aug 14, 2015) Please give exact correct explanation simple method.

 Rajendiran S said: (Aug 29, 2015) 1000 = 1*10^3. 5000 = 5*10^3. 65000 = 65*10^3. = 6.5*10^(3+1). = 6.5*10^4.

 Stephen said: (Sep 11, 2015) Am not clear with the answers given, please can you give simple solution to this question?

 Mehmood said: (Jan 13, 2016) Remember if we change in fraction must add 1.

 Raghuwansh said: (Apr 24, 2016) Nice. Thank you all for explaining the problem.

 Kailash Meher said: (Sep 11, 2016) Thank you to all for explaining the problem in an easy way.

 Shivaraj said: (Jan 12, 2017) I understand now, Thank you all for explaining the problem.

 Saritha said: (May 27, 2017) 65,000. 65 * 1000 = 65*10^3. 65 * (10/10) * 10^3. (65/10) * (10^1*10^3). 6.5 * 10^4. {a^m*a^n=a^(m+n)}.

 Chandru said: (Jun 9, 2017) Thank you all for the given explanation.

 Muzaffar Baba said: (Mar 26, 2018) Sol: 65000= 65*1000 = [65*10^3] = [65/10 * 10 * 10^3] {Multiple & divide 65 by 10}. = [65/10 * 10 * 10^3 {10^3 3 is raised power 10}, = [65/10 * 10^4] {bases are same powers are added i.e 10^1 * 10^3=10^4}, = [6.5*10^4] {65/10=6.5}. So, the Answer is (B).

 Ifeanyi Solomon said: (May 10, 2018) According to me, it should be 65*10^3.

 Vishnu Priya said: (Jun 20, 2018) I can't understand clearly. Please explain to me.

 Avijit Hazra said: (Jul 8, 2018) I can't understand. Please explain the solutions.

 P.Jagatheeswaran said: (Nov 12, 2019) I need perfect explanation for this question if you know please explain to me.

 Er.Rajwinder Singh said: (Dec 12, 2019) Its simple look all given options and proper read question we already found the number between 1 to 10. look A option 0.65, c option 65 and last D 650 each are lie between 1 to 10 so answer is clear 6.6 x 10>4
