" 111."sqrt(1(9)/(16))=?

Find the value of sqrt(1(9)/(16))

9.Evaluate sqrt((0.289)/(0.00121))+sqrt((64)/(16))

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))

int sqrt(9x^(2)+16)dx=?

Evaluate the following: 2/3xx sqrt((-9)/16) .

sin^(-1)(-3/4)=-cos^(-1)sqrt(1-9/16)=-cos^(-1)((sqrt(7))/4)

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

cos^(-1)((-3)/4)=pi-sin^(-1)sqrt(1-9/16)=pi-sin^(-1)((sqrt(7))/4)
