*Homework answer* =7+77+777+7777+......n terms =7(1+11+111+.......n terms) Multiply and Divide by 9, we get =7/9(9+99+999+....n terms) =7/9[(10-1)+(10²-1)+(10³-1)+....n terms] =7/9[(10+10²+10³+....n terms)-(1+1+1....n terms)] Thus it is in G.P,we can write it as =7/9[10×(10^n-1)/9 -9] HO GYA SIR 🙏
Sir I request the Physics Wallah family to start a new accelerate for class 12 from April So,that class 11 passing out students can read in 4 months Please please sir We request to you start a new batch for class 12 students from April 🙏🙏🙏🙏🙏🙏🙏 We are humbled and grateful for your speechless qualitative education Please sir 🙏🙏🙏🙏🙏
41:42 answer of hw question = 70/81 (10^n-1) - (7n/9) whatever you taught or made me understand, i have understood very well Thank you so much guru jii ❤️
Last step mein minus n nahi karengey ? ...kyuki 1 baar baar plus ho rha h ...n times tak plus hoga ....aur 1 k bracket k Bahar minus ka sign hai to ....last mein final answer ye hona chahiye 7/9 [{10(10^n-1)/9} - n ]
7[10/81(10^n-1) -n/9] Just take 7 common then multiply and divide by 9 then proceed with the same process as sir told Hope you like it if any correction please let me know below
40:54 Answer is 70/81(10^n-1)-n Take 7 as common and then multiply and divide by 9....Then Convert the sequence given in the bracket into GP.... Atlast we'll get our answer.
I tried the home work question and the answer is =70/81(10^n-1)-7n/9 this is the sum of n terms of the series and i love the way you teach sir instead you change the channel but respect for your teaching
Sir yesterday's Homework question I did with the same method as you told today sir 🙏🙏🙏🙏 and the answer of the homework question is 7/9{10(10^n -1)/9 -n} Take 7 /9 as comman and then proceed as sir has told in one question
41:41 Answer : 10(10^n-1) - 2(10^n-1 -1) -3{(10^n-1-1) -3{(10^n-2-1) - (10^n-3-1) -(10^n-4-1)-................... -(10^2-1)-(10^1-1)} ans....... I tried so much but can't make its simplified form 😞

*Homework answer*
=7+77+777+7777+......n terms
=7(1+11+111+.......n terms)
Multiply and Divide by 9, we get
=7/9(9+99+999+....n terms)
=7/9[(10-1)+(10²-1)+(10³-1)+....n terms]
=7/9[(10+10²+10³+....n terms)-(1+1+1....n terms)]
Thus it is in G.P,we can write it as
=7/9[10×(10^n-1)/9 -9]
