Q695.Find d/dx of (2x + 3)⁴:

Medium
A 4(2x + 3)³
B 8(2x + 3)³
C 16(2x + 3)³

0.00416 = 4.16 / 1000 = 4.16 * 10^-3.

Q697.What is the value of (1,000,001)² − (999,999)² ?

Medium
A 2,000,000
B 4,000,000
C 6,000,000
D 8,000,000
Other PPSC

Correct Answer: B

Applying the difference of squares identity (a² - b²) = (a - b)(a + b). Let a = 1,000,001 and b = 999,999. Thus, (1,000,001 - 999,999)(1,000,001 + 999,999) = 2 × 2,000,000 = 4,000,000.

Medium
A 1
B 99
C 100
D 199
Other PPSC

Correct Answer: D

(100)² - (99)² = (100 - 99)(100 + 99) = 1 × 199 = 199.

Q699.What is the cross product of 2D vectors (1, 0) and (0, -1)?

Medium
A 1
B -1
C 0
D 2
Other PPSC

Correct Answer: B

For 2D vectors u=(u1,u2) and v=(v1,v2), the cross product magnitude is u1*v2 - u2*v1. Here, (1 × -1) - (0 × 0) = -1.

Q700.What is the value of sin(θ) × cos(90°)?

Medium
A 1
