Question

(3×10⁴)+(4×10³) solutions I need​

Answer 1

(3×10×4) that is written in the form of (3×10⁴)

now,

multiply 10⁴ it means 10×10×10×10 so you will get 200

now, you just multiple this 3×200 you will get 600

Now,

take (4×10³) and do the same like the above

multiply 10³ it means 10×10×10 so you will get 150

now, multiply this two no. 4×150

you will again get the same 600

Now,

Add this sum

(3×10⁴)+(4×10³)

= 600+600

=1200

It's very simple!
