Video solution:

=>789.009-x+56.84=215.943

=>x = 789.009+56.84-215.943

=>x = 845.849-215.943

=>x =629.006Ans.



Video solution:

12^4.5 x 12^a = 12^5.6 x 12^1.8

=>12^a =(12^5.6 x 12^1.8)/12^4.5

=>12^a=12^7.4/12^4.5

=>12^a=12^2.9

=>a=2.9



Video solution:

let, A=9.99x9.9x9=890.91

let, B=A/9.9/0.3

So, B=(890.91/9.9)/0.3

=>B=(89.9909091)/0.3

=>B=299.96

Now, 1% of B = 299.96/100 = 2.9996



Video solution:

=>0.3x10^-3

=>0.3/1000

=>0.0003Ans.
