Simplify the following expressions;
ln e3
ln e2y

ln e^3 =3

ln e^2y =2y

Step-by-step explanation:

The natural logarithm and the rational number e are inverse functions. This implies they neutralize or simply cancel out each other. In this case, the solution is simply the value in the exponent.

In general;

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
