1.	If Sin4A/a +cos4A/b =1/a+b,then prove that sin8/Aa³ +cos8A/b³=1/(a+b)³.
Answer» Mujhe bhi 10th ki worksheet mein hi Mila hai When ethyne is burnt in air incomplete burning takes place and produce sooty flame due to limited supply oxygen present in the air. ... Hence, This oxy-acetylene flame is used for welding and it is not possible to attain such a high temperature with air. Due this reason a mixture of ethyne and air is not used for welding. Great.But we cant answer bcuz our level is 10th.We cant solve a 12th level question 10th mein 12th ka
