3²x3 ^x= 3^7
Find the value of x

the answer is 3^5 because multiplication is done by adding the carriers

x = 5

Step-by-step explanation:

Rewrite the equation

3^x+2=2187

perform prime factorization of the right side

2187=3^7

3^x+2 = 3^7

equate the exponents of 3 on both sides

x+2 = 7

solve for x

x=5

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
