Question

10i² - 6i³ +13i^4 - 6i³ =

Answer 1

Step-by-step explanation:

Principal (p) = Rs 1000 Rate (r) = 8% Time = 1 ½ years = 3/2 × 2 = 3 half years By using the formula, A = P (1 + R/100) n = 1000 (1 + 8/100)3 = 1000 (208/100)3 = Rs 1124.86 ∴ Compound Interest = A – P = Rs 1124.86 – Rs 1000 = Rs 124.86

Answer 2

${\underline{\boxed{\mathfrak\red{Question}}}}$

10i² - 6i³ +13i^4 - 6i³

${\underline{\boxed{\mathfrak\red{Answer}}}}$

⇒10(-1) - 6i².i + 28561 .1 -6i².i

⇒-10 - 6(-1) .i + 28561 - 6(-1).i

⇒-10 + 6i + 28561 + 6i

${\underline\purple{⇒28 551 + 12 i}}$
