Question

3^x+4=7^x-1

Answer 1

is it 3 to the power x or x to the power 3 ?

Answer 2

3 to the power of x

Answer 3

ohk , wht u do is , just do a little transfer of terms
7^x-3^x=4+1
so
7^x-3^x=5

Answer 4

now start putting the values of x on the Left hand side
if x=0 , then 7^x is 7^0=1
1-1=0 so this is not equal to 5 that is rigt hand side, dump this value of x,
Carry on to next value of x
if u put x=1, ummm then also not working :(

Answer 5
