If , sT = \(\sqrt{\frac{[(a + T)T]}{a}}\) what does T equal?
T = (a2s2 – 1)
T = (a2s2– 1) ÷ a
T = a ÷ (a2 - s2)
T = a ÷ (a2s2 – 1)
T = (as – 1)2

1.995 × 103
1.95 × 102
1.95 × 101
1.95 × 10-2
1.95 × 10-3
Correct answer is C
Where 1.25 × 10\(^2\) = 125
0.125 × 10\(^3\) = 125
12.5 × 10\(^{-4}\) = 0.00125
: 125 x 125 x 0.00125
= 19.53125 or 1.95 x 10\(^1\)

Correct answer is D
U = {14,15,16,17,18,19,20}
J' = {14,15,17,18}
K' = {16,17,19,20}
(J' \(\cap\) K') = {17}
(J' \(\cap\) K')' = {14,15,16,18.19,20}
