The C.S.A. and T.S.A. of cylinder are in the ratio 1:2. If the T.S.A of the right cylinder is 616 sq. cm, then find its volume?

M ∠ A = (4x + 3)° and m ∠ B = (5x + 6)°
Find the value of x if the angles A and B are
I) Complementary

Simplify using the laws of exponents:

If   and  , what is one possible value of   ?

Note:
This problem can have different answers if solved differently. Instead of making   positive, if we took  , we would get a different answer. Similarly,  for  , we get a different value of  . If we take both negative, we will get another answer.
Thus, we can get 4 answers: 1,3, 4, 12.
