simplify 9² x 9 to 9³

9³ x 9⁵/9⁹

use product rule: x‸ax‸b=x‸a+b

9⁸/9⁹

use quotient rule: x‸a/x‸=x‸a-b

9⁸⁻⁹

simplify 8-9 to -1

9⁻¹

use negative power rule: x‸-a=1/x‸a

1/9
So basically using pemdas (parentheses,exponents,multiplication ,division, addition , subtraction) 9 times 2 is 18 so that would make the numerator 18*9*9^5 . Moving on to the denominator it’s it’s 81 . Next is multiplication so 9 times 5 is 45 so making it 18 times 9 times 45 so multiple 18 times 9 and you get 162 and 162 times 45 is 7,290 . You are left with 7,290/ 81 and you would basically get 90 because it 7,290 goes into 81 around 90 times so it would be 90/1 HOPE IT HELPS PLEASE MARK ME BRAINLIEST I WOULD HIGHLY APPRECIATE IT :))
