The mean of the numbers `52, t` and `68` is `61` What is the value of `t?`

If t^(3)=-8 , what is the value of t^(2) ?

If t gt0 and t^(2)-4=0 , what is the value of t ?

If u+t=5 and u-t=2 , what is the value of (u-t)(u^2-t^2) ?

If 8^(r)=4^(t) , what is the value of r to t?

The mean of the following numbers is 68. Find the value of 'x'. 45, 52, 60, x, 69, 70, 26, 81 and 94. Hence, estimate the median.

If for an A.P., d=20, what is the value of t_6-t_2?

If ( t + 5 ) /( t - 5 ) = 10 , what is the value of t ?

If for an A.P., d=10 , what is the value of t_(6)-t_(2) ?
