Answer 1

Hello your answer is..........

Given ,

= 3/(216) - ( 2/3 ). + 2 /(256) - ( 3/4) + 2/ ( 243 )-

(1/5)

= 3 / 72 - ( 2/3) + 2 /(128) - (3/4) + 2 / ( 243) -

( 1/5)

= 3/ 24 - (2/3) + 2 / ( 64 ) - (3/4) + 2/(243) - (1/5)

= 1/8 - (2/3) + 1/32 - (3/4) + 2/(243) - (1/5)

= 0.125 - 0.666 + 0.03125 + 0.75 + 0.0082305 -
0.2

= 0.125 + 0.03125 + 0.76 + 0.0082305 - 0.666

= 0.9244805 - 0.666

= 0.2584805
