Answer 2

6 . (3^-1 + 4^-1 +5^-1)^0=1 ( IF ANY NO. IS HAVING POWER 0 THEN ITS VALUE WILL BE ONE)

7. 4^-1 + 8^-1 / (2/3)^ -1
=I/4 + 1/8 / (2/3) -1
= 2 /8 /3/2 ( TAKING LCM  OF 8)
= 2/8* 2/3 
=1/6 ANS

8. 352000

9. 0.837 8* 10^8
 10. 1.0008/10000000
11. 6^-1 *1/6*36
=1/6*1/6*36 (CANCELLING THE NO.)
=1 ANS
12.( 1/2 + 1/3 ) ^2
= (2+3/6) ^2
=(5/6)^2
=24/36
13. ( 1/2+1/3 )^-1
=( 2+3/6)^-1
= ( 5/6) ^-1
= 6/5
14. (1/4) ^-4 *(1/4)^-8=(1/4)^-4X
= (1/4)(-4)+(-8) = (1/4) ^-4X
=(1/4)^-12=(1/4)^-4X  (IF NO. ARE EQUAL THE POWER SHOULD ALSO BE EQUAL)
THEN, -12=-4X
= X=-12/-4
=X= 3 ANS.
15.  (3^-1+ 4^-1) / 5^-1
= (1/3+1/4 ) /5^-1
=(4+3/12)/5^-1
=(7/12)/1/5
=7/12*5
=35/12 ANS.
16. [{(-1/3)^2}-2]-1
= (-1/3)^2*-2*-1
=(-1/3)4
=1/81 ANS.
