12.1+(4)/(3)+(9)/(3^(2))+(16)/(3)+(25)/(3^(4))+

Sum of infinite terms of the series 1 + 4/7 + (9)/(7^2) + (16)/(7^3) + (25)/(7^4) +……, is

What is the value of ((3)/(4) div (9)/(32) +(4)/(3) xx (2)/(3) " of "(27)/(16))/((1)/(2) xx ((8)/(2) -2) div (4)/(9) +((1)/(3)+(1)/(6))) ? (a) (10)/(3) (b) (13)/(2) (c) (25)/(2) (d) (31)/(2)

(1) (4)/((216)^((2)/(3)))+(1)/((256)^((3)/(4)))+(2)/((243)^((1)/(5))) (ii) ((64)/(125))^((2)/(3))+((256)/(625))^((1)/(4))+((3)/(7))^(0) (iii) ((81)/(16))^((3)/(4))(((25)/(9))^((3)/(2))-:((5)/(2))^(-3)) (iv) ((25)^((5)/(2))times(729)^((1)/(3)))/((125)^((2)/(3))times(27)^((2)/(3))times8^((4)/(3)))

Simplify : [ ((- 3 )/( 2) xx (4)/(5) ) + ((9)/(5) xx (-10)/( 3)) - ((1)/(2)xx (3)/(4)) ] div [ ((21)/( 9) xx (3)/(7)) +((7)/(8) xx (16)/(14)) ]

sqrt((25)/(81)-(1)/(9))=?(2)/(3)( b) (4)/(9)( c) (16)/(81) (d) (25)/(81)

The value of ((9^(2)xx18^(4))/(3^(16))) is a.(3)/(2) b.(4)/(9) c.(16)/(81) d.(32)/(243)

Name the property used in the following. (1)/(3)+((4)/(9) +((-4)/(3)))=((1)/(3)+(4)/(9))+((-4)/(3))
