The sum of 7 to the 9th power and y is expressed as 7⁹ + y
This statement will result in an exponential equation since we will have a base and an exponent
- 7 raise to the 9th power is expressed as 7⁹
- Taking the sum of the result and y;
- The final expression will be 7⁹ + y
Hence the sum of 7 to the 9th power and y is expressed as 7⁹ + y
