This is because the base is the same for both of them (3). The denominator of the exponent will always be whichever root is taken (fifth in this case). The numerator is what the number is being raised to (2). Therefore, the exponent (a) is 2/5.

WebYou can now solve for the final value of m. To eliminate the -8 from the left side of the equation, add 8 to each side of the equation: 9m - 8 + 8 = 28 + 8. 9m + 0 = 28 + 8. 9m = 28 + 8. 9m = 36. To eliminate the 9 from the left side of the equation, divide each side of the equation by 9: 9m = 36. 9m/9 = 36/9.
