An <em>imaginary number</em>. The defining property of an imaginary number is that has the number i attached to it, where i² = -1.
A few examples of imaginary numbers: 3i, i, -7i, (√3)i, (1/2)i
1 (((m^(-1)) (m^5)) / (m^(-2)))^(-3) =1/m^18
Using the quadratic formula
Answer:
RS 14400
Step-by-step explanation:
Given the following :
Principal sum = RS 40000
Rate = 2 paisa per 2 rupee per month
Interest at the end of 3 years
1 rupee = 100 paisa
2 Paisa per 2 rupee per month :
2/200 per month = 1 / 100 per month,
Hence rate = 0.01 = 1% monthly
Annual rate = 1% × 12 = 12 % = 0.12
Simple interest :
Principal × rate × time
40000 × 0.12 × 3
40000 × 0.36
= RS 14,400
