      a3 + b3 is actually a3 ^+ b3. so it will b equal to (a+b) ^3 – 3ab(a+b). Put d values n get d answer

  3. From the question organic chemistry

    1 mole of br2(bromine gas) attak on 1 mole of alkene and 1 mole of br2 attack on 1 mole of alkyne. the rxn is anti addition by markovni’s rule.since Br-Br bond gets broken in to Br+ and Br- bromine colur gets discharged to become colour less

    u must be thinkig that 2 moles of bromine should attack 1 mole of alkyne? but thats not so

  4. From the question electric current

    i totally agree with Mr RAj Beniwal.wat Mr ragav wrote was individual power dissipated across each resistence n also r is negligible so we cant equate IxIxr=IxIxR bcoz both of them are differnt.

    am i clear??
