Find the value of (4\(^{\frac{1}{2}}\))\(^6\)
1
2
4
6
64
Correct answer is E
The powers will multiply when the bracket is expanded
The multiplied powers: \(\frac{1}{2}\) * 6 → 3
: 4\(^3\) = 4 * 4* 4
→ 64
If x3 - 12x - 16 = 0 has x = -2 as a solution then the equaion has
x = -4 as a solution also
3 roots all different
3 roots with two equal and the third different
3 roots all equal
only one root
Correct answer is B
No explanation has been provided for this answer.
Solve the simultaneous linear equations: 2x + 5y = 11, 7x + 4y = 2
x = -8, y = 1
x = -2, y = 4
x = \(\frac{-34}{27}\), y = \(\frac{73}{27}\)
x = 7, y = -9
Correct answer is C
2x + 5y = 11.......(i)
7x + 4y = 2.......(ii)
(i) x 7 \(\to\) 14x + 35y = 77.........(iii)
(ii) x 2 \(\to\) 14x + 8y = 4........(iv)
(iii) - (iv)
27y = 73
y = \(\frac{73}{27}\)
1\(\frac{2}{3}\)

Correct answer is C
Let x rept. the usual speed = \(\frac{Distance}{Time}\)
= \(\frac{20}{1}\) x \(\frac{1}{2}\)
= 5
(a), (b), (c)
(c)
None of the choices
All of the above
Correct answer is B
0 < \(\frac{x + 3}{x - 1}\) < 2
Put x = 0, -3 and 9
0 < \(\frac{9 + 3}{9 - 1}\) \(\leq\) 2
i.e. 0 < 1.5 \(\leq\) 2 (true)
but 0 < \(\frac{0 + 3}{0 - 1}\) \(\leq\) 2
i.e. 0 < -3 \(\leq\) 2 (not true)
-3 \(\leq\) 2
-3 is not greater than 0
