Answer» IS 5Explanation:[Any NUMBER (say x) RAISED to the power some number (say n) can also be written as x^n](17/19)^7 * (19/17)^-8 = (17/19)^3X =⟩ (17/19)^7 * (17/19)^8 = (17/19)^3x [Sign of the power is reversed when reciprocal is DONE]=⟩ 7+8=3x [Since all the abses are same, hence the powers are also same]=⟩ 15=3x=⟩ x=15/3 = 5 |
