Correct answer is D
Given that, a * b = a2b and a ^ b = 2a + b
(-4 * 2) = (-4)2 x 2 = 16 x 2 = 32
(7 * -1) = 72 x (-1) = 49 x (-1) = -49
∴ (-4 * 2) ^ (7 * -1) = 2(32) + (-49) = 64 - 49 = 15

x = 2,3
x = 0,3
x = 12, 13
x = 12, −13
Correct answer is C
6x2 = 5x - 1
→ 6x2 - 5x + 1 = 0
Factorization:
factors are -3x and -2x
6x2 - 3x -2x + 1 = 0
(6x2 - 3x) (-2x + 1) = 0
3x(2x-1) -1(2x-1) = 0
(3x-1) (2x-1) = 0
x = 12, 13
Given that log3 27 = 2x + 1, find the value of x.
0
1
2
3
Correct answer is B
Recall that: log3 27 → log333
3log33 → 3 * 1
= 3
Then log3 27 = 2x + 1
→ 3 = 2x + 1
3 - 1 = 2x
2 = 2x
1 = x
