If 0.0000152 x 0.042 = A x 108, where 1 (leq) A
- A.
A = 9, B = 6.38 - B.
A = 6.38, B = -9 - C.
A = -6.38, B = -9 - D.
A = -9, B = -6.38
Correct Answer: Option B
Explanation
0.0000152 x 0.042 = A x 108
1 (leq) A
0.0000152 = 1.52 x 10-5
0.00042 = 4.2 x 10-4
1.52 x 4.2 = 6.384
10-5 x 10-4
= 10-5-4
= 10-9
= 6.38 x 10-9
A = 6.38, B = -9
