" Q...Smplify ":7^((1)/(2)).8^((1)/(2))

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

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

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

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

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)

Simplify ((q^(3-7q)xxq^(6-2q))/(q^(2q)xxq^(9-2q)))^(1/9) .

Let S=(0.7)^(log_(0.49)((1)/(8)+(1)/(8^(2))+(1)/(8^(3))+...),
