(7)^((1)/(2))(8)^((1)/(2))" at ser ont "

Simplify (7^(1/2).8^(1/2))

The value of 7^((1)/(2)).8^((1)/(2)) is

Solve : (i) 2^((2)/(3))*2^((1)/(4)) (ii) ((1)/(3^(3)))^(7) (iii) (11^((1)/(2)))/(11^((1)/(4))) (iv) 7^((1)/(2))*8^((1)/(2))

Simplify : (i) 2^(2//3).2^(1//5) (ii) ((1)/(3^(3)))^(7) (iii) (11^((1)/(2)))/(11^((1)/(4))) (iv) 7^(1//2).8^(1//2)

Simplify : 7^((1)/(2)) * 8^((1)/(2))

x^(2)+(1)/(x^(2))-7(x-(1)/(x))+8

If z^(7)+1=0 then cos((pi)/(7))cos((3 pi)/(7))cos((5 pi)/(7)) is (A)(1)/(8) (B) -(1)/(8)(C)(1)/(2sqrt(2))(D)(1)/(2)

(7)/(8)+(3)/(4)((1)/(2))(2)/(3)-(1)/(3))
