" 12."10^((10^(x)))

The inverse of (10^(x)-10^(-x))/(10^(x)+10^(-x)) is :

The inverse of the function (10^(x)-10^(-x))/(10^(x)+10^(-x)) is

The domain of (10^(x) +10^(-x))/(10^(x)-10^(-x)) is:

(x-2)^(log_(10)^(2)(x-2)+log_(10)(x-2)^(5)-12)=10^(2log_(10)(x-2))

((100^(12))(10^(4)))/(10^(2))=

Let X=(^(10)C_(1))^(2)+2(^(10)C_(2))^(2)+3(^(10)C_(3))^(2)+...+10(^(10)C_(10))^(2) where ^(10)C_(r),r in{1,2,;10} denote binomial coefficients.Then,the value of (1)/(1430)X is

If alpha and beta are the roots of the equation x^(2)+10x-7=0 then the value of (alpha^(12)+beta^(12)-7(alpha^(10)+beta^(10)))/(2(alpha^(11)+beta^(11))) is

If sum_(i=1)^(10)(x_(i)-15)=12 and sum_(i=1)^(10)(x-15)^(2)=18 then the S.D.of observation x_(1),x_(2),x_(3),....x_(10) is:
