Question

calculate the amount and compound interest for the following, if interest is compounded annually

i) P =₹8000;R=10%p.a.; Time =2Years

ii) P =₹10,000;R=7%p.a.; Time =3Years ​

Answer 1

Answer:

Rewrite equation with the term containing cube root on one side as follows. 3√x = x.

Raise both sides to power 3 in order to clear the cube root. ( 3√x ) 3 = x 3

Rewrite the above equation with right side equal to zero. x - x 3 = 0.

Factor. x (1 - x 2) = 0.

and solve for x.
