Find the value of t for which \(\frac{64}{27} = (\frac{3}{4})^{t - 1}\)
-4
-2
11/3
2
4
Correct answer is B
\(\frac{64}{27} = (\frac{3}{4})^{t-1}\)
\((\frac{3}{4})^t = \frac{64}{27} \times \frac{3}{4} = \frac{16}{9}\)
\((\frac{3}{4})^t = (\frac{9}{16})^{-1}\)
\((\frac{3}{4})^t = (\frac{3}{4})^{-2}\)
t = -2

Correct answer is B
r = log9/log3 = 2log3/log3 = 2
The eleventh term of an AP, is 25 and its first term is -3. Find its common difference.
19/10
21/5
23/11
21/2
24/5
Correct answer is E
a + 10d = 25
-3 + 10d = 25
d = 28/10 = 24/5
