In algebra the notation is basically just a number, for example, 10, and we take it to the 10th power, you just take the decimal at the end of the 10 and move it 10 spaces to the right, if the number is negative you will move the decimal to the left 10 spaces, the 10th power is a variable and is different with every question
The answer is (4/9)^11 since it is addition you add the powers however the fraction has to be the same in order for it to work same for division but division is subtraction
