Question

3 to the power x minus 1 is equal to 9 and 4 to the power Y + 2 equal to 64 find the value of y /x-x/y

Answer 1

Y/X-X/Y= - 8/3. WHICH IS THE REQUIRED ANSWER

Answer 2

according to the question

3^x-1 = 9

so

x-1 = 2

therefore x = 3

also

4^y+2 = 64

so

y=1

now 1/3 - 3

-8/3 is the answer
