If 2n = y, Find 2\(^{(2 + \frac{n}{3})}\)

A.

4y\(^\frac{1}{3}\)

B.

4y\(^-3\)

C.

2y\(^\frac{1}{3}\)

D.

2y\(^-3\)

Correct answer is A

If 2n = y,

then, 2\(^{(2 + \frac{n}{3})}\) = 22 x 2\(^\frac{n}{3}\)

= 4 x (2n)\(^{\frac{1}{3}}\)

But y = 2n, hence

2\(^{(2 + \frac{n}{3})}\) = 4 x y\(^{\frac{1}{3}}\)

= 4y\(^\frac{1}{3}\)

Given that logx 64 = 3, evaluate x log\(_2\)8

A.

6

B.

9

C.

12

D.

24

Correct answer is C

If logx 64 = 3, then \(64 = x^3\)

\(4^3 = x^3\)

Since the indices are equal,

x = 4

Hence, x log\(_2\)8 

= 4(3.log\(_2\)2)

= where log\(_2\)2 = 1(1)

= 12 X 1 

= 12
