Question

PLS solve this maths problem​

Answer 1

Answer:

2³×5²

Step-by-step explanation:

Firstly, Write (4×10⁸) = (2×2)×(2×5)⁸

Now, (6×10–⁵)= (2×3)×(2×5)–⁵

So, Now we have got

(2×2)×(2×5)⁸×(2×3)×(2×5)–⁵

2¹×2¹×2⁸×5⁸×2¹×3¹×2–⁵×5–⁵

Now, Here we can see that 2 has a lot of base. Now we will add this

2¹×2¹×2⁸×2¹×2–⁵= 2¹¹+(-5) = 2⁶

Now the left digits are:-

5⁸×5–⁵= 5³

So, 1st row answer is= 2⁶×5³×3¹

So, Now we will solve 2nd row:- 12×10⁴

(2×2×3)×(2×5)

(2²×3)×(2×5)

Now add those digits which has similar base:- 2²+2¹= 2³

So, we got= 2³×3¹×5¹

Now we will solve the question

2⁶×5³×3¹

------------

2³×3¹×5¹

2⁶-³×5³-¹×3¹-¹

2³×5²×3⁰

2³×5²×1

Hence, The answer is 2³×5²
