If 3\(^{2x}\) = 27, what is x?
1
1.5
4.5
18
40.5
Correct answer is B
p>3\(^{2x}\) = 27
3\(^{2x}\) = 3\(^3\)
2x = 3
x = 1.5
Simplify 125\(^{\frac{-1}{3}}\) x 49\(^{\frac{-1}{2}}\) x 10\(^0\)
350
35
1/35
1/350
Correct answer is C
125\(^{\frac{-1}{3}}\) x 49\(^{\frac{-1}{2}}\) x 10\(^0\)
= 5\(^{-1}\) x 7\(^{-1}\) x 1
= \(\frac{1}{35}\)

51/2
Correct answer is B
1st term a = 2; 6th term = a + (16-1)d = 2 + 5d
2 + (2 + 5d) = 161/2; 4 + 5d = 161/2
5d = 12.5 ∴ = 2.5
the 4th term is 2 + (4-1)2.5= 91/2
In the diagram, O is the center of the circle, If ∠POQ = 80o and ∠PRQ = 5x, find the value of x.
4o
8o
16o
20o
32o
Correct answer is B
80o = 2 x 5x(angle at the center)
=80o = 10x; x = 80o/10
= 8o

Correct answer is A
Probability that 3 customers are attended to in the sequence they arrive
= prob of attending to the 1st arrival x prob of attending to the second last x prob of attending to the last
= \(\frac{1}{3} \times \frac{1}{2} \times \frac{1}{1}\)
= \(\frac{1}{6}\)
