Trenton said that 9 to the power of three times 9 to the power of eight ( eight is negative) = nine to the power of 5 (5 is negative). Kendal said 9 to the power of three times 9 to the power of 8(8is negative) = 1/9 to the power of 5.Determine who is correct .justify your answer
Both are correct. Trenton 9^3 x 9^-8 = 0.0000169351 or 9^-5. 3 + -8 = -5. Kendal 9^-1 = 0.1111111111 or 1/9 9^-2 = 0.012345679 or 1/9 divide 9. Which is just 1/9 x 1/9. Or 1/9^2. 9^-2 = 1/9^2 Therefore, 9^3 x 9^-8 = 9^-5 or just 1/9^5.
