How do we solve exponential equations ?

 How to solve 100 +10 ^x where the 'x' is unknown but you that 10 *10 is 100 so "x' equals 2
When the bases/ numbers are the same the exponents must be equal as well
solve for 3^x+4 = 3^7
first just set up the exponents like an equation : x+4 = 7 , the solve algebraically
x will equal =11
11 is the new exponent

 Try this with ; 2 ^3x+7 = 2^5x-1
  set up the exponents 3x+7 =5x-1 then solve algebraically
then end result will be that x= 4 this becomes the new exponent
