Answer = 5.6×10⁴
Solution = (Given) 5.8×10⁴ - 1.5×10³
Changing 1.5×10³ into 0.15×10⁴ (without disturbing the order of significant figures as ALAKH SIR said - 46:26 )
Now
5.8×10⁴ - 0.15×10⁴
(5.8 - 0.15)10⁴
5.65×10⁴
Now rounding off at, least decimal place we get 5.6×10⁴ (no change in magnitude 10⁴ while doing rounding off process)

2022-2023 still old lectures are best than new lectures
🔥☀️⚡💥Fire - Alakh Sir

2023-2024 batch students still came to understand such topics by our only Alakh Sir.🎉

The answer of addition And subtraction is:-
5.8*10^4 -1.5*10^3
=5.8*10^4 -0. 15*10^4
=10^4(5.8-0.15)
=10^4(5.650)
Rounding off to one decimal:-
=5.6*10^4
👉Hence solved😇

Let me know how many Students are there from batch 2023-2024...😅😁

5.8 × 10⁴ - 1.5 × 10³
→5.8 × 10⁴ - 0.15 × 10⁴
→(5.8 - 0.15) × 10⁴
→5.65 × 10⁴
[5.8 have 1 decimal place or least decimal place so round of to 1 decimal place]
→5.6 × 10⁴ = Answer

ANS SOLUTION.

5.8×10^4 - 1.5×10^3
58000-1500=56500.

It can also be written as 5.65×10^4.

Ab 5.8 & 1.5 mai decimal places 1 hai tou ans mai bhee ek.

Ab 5.65 rounded off to 1place after decimal. 5.650 piche 50 hai aur 5 ke piche even hai isliye jaisa hai waisa hee rahe ga.

In short
5.6×10^4(5=5 followed by 0, and 6 is even).

[missriya]

49.27 ans is 5.8 x 10^4 - 1.5 x 10^3 = 5.8 x 10^4 - 0.15 x 10^4 = 5.65 x 10^4..by rounding off we get 5.6 x 10^4

2027 - 2028 wale attendance here 👇🏻. Disclaimer jo hai future se sirf vo hi attendence lagana🫣

[sanjaymishra]

48:22 ka solution
5.8 x 10^4 -1.5 x 10^3
=5.8 x 10^4 - 0.15 x 10^4
=10^4(5.8-1.5)
=5.6 x 10^4

Alakh pandey is the best teacher who ever feels it like it👇👇👇👇👇👇👇👇👇👇👇👇

[singamthirupathi]

Answer for the question is 5.6×10^4
5.8×10^4 - 1.5×10^3
5.8×10^4 -0.15×10^4=5.65×10^4
On rounding off 5.65×10^4
We will get 5.6×10^4
