(sqrt((225)/(729))-sqrt((25)/(144)))-sqrt((16)/(81))

Solve: (sqrt((25)/9)-sqrt((64)/(81)))-:sqrt((16)/(324))=? (a) 4.5 (b) 2.5 (c) 1.5 (d) 3.5

sqrt((324)/(81))+sqrt((324)/(81))=?

sqrt((81)/(64)sqrt((81)/(64))sqrt((81)/(61))sqrt((81)/(64))...oo)=

Evaluate the following: (i) sqrt(-81) (ii) (sqrt(-2))^(6) (iii) sqrt(-25)xxsqrt(-49) (iv) (2)/(3)xxsqrt((-9)/(16)) (v) sqrt((-49)/(25))xxsqrt((-1)/(9))

sqrt((81)/(64)sqrt((81)/(64)sqrt((81)/(64)sqrt((81)/(64)))).........oo=)

(sqrt(81)+sqrt(729))/(sqrt(225)-sqrt(9))=

Perform the indicated operation and find the result in the form a+ib.(2-sqrt(-25))/(1-sqrt(-16)) (ii) (3-sqrt(-16))/(1-sqrt(-9))

sqrt(3^(2)sqrt(9^(2)sqrt((81)^(2)sqrt(16)^(16)))) =______.
