Arrange the following numbers in descending orders of magnitude: 22three, 34five, 21six

A.

21six, 22three, 34five,

B.

21six, 34five, 22three

C.

22three, 34five, 21six

D.

34five, 21six, 22three

Correct answer is D

22three, 34five, 21six = (2 x 3)(2 x 3o), (3 x 51) = (4 x 50), (2 x 61) + (1 x 60)

= (6 + 2), (15 + 4), (12 + 1) = 8ten, 29ten, 13ten in descending order

29ten, 13ten, 8ten = 34five, 21six, 22three

If log 2 = x, log 3 = y and log 7 = z, find, in terms of x, y and z, the value of log (\(\frac{28}{3}\))

A.

2x + y - z

B.

2x + z - y

C.

x + y - 2x

D.

x + x - y

Correct answer is B

log (\(\frac{28}{3}) = \log (\frac{7 \times 4}{3})\)

= log 7 + log 4 - log 3

log 7 + log 22 - log 3 = log 7 + 2 - log 3

= z + 2x - y

= 2x + z - y
