`((15)/(16))^(3)-:((9)/(8))^(2)`

(1)/(2)+(3)/(4)+(9)/(8)+(27)/(16)+... oo

Prove that: ((1)/(4))^(-2)-3x8^((2)/(3))x4^(0)+((9)/(16))^(-(1)/(2))=(16)/(3)

(16(2)/(5)-12(1)/(15))-:3(4)/(81)=?( a) 1(9)/(19) (b) 1(9)/(13)(c)2(8)/(13) (d) 3(2)/(19) (e) None of these

The coefficient of x^(3) in the infinite series expansion of (2)/((1-x)(2-x)), for |x|<1 is (A)-(1)/(16)(B)(15)/(8)(C)-(1)/(8)(D)(15)/(16)

The value of (19^(3)+6^(3)+(3)(19)(6)(25))/(3^(6)+6(243)(2)+(15)(81)(4)+(20)(27)(8)+(15)(9)(16)+(6)(3)(32)+2^(6)) is

Evaluate : [(1)/(4)]^(-2)-3(8)^((2)/(3)) xx 4^(0) + [(9)/(16)]^(-(1)/(2))

((-9)/(16)xx(8)/(15))=?

Multiply: (8)/(-9)by(-7)/(-16) (ii) (-8)/(9)by(3)/(64)
