回答 (7)
✔ 最佳答案
(25/9)^2
= (25^2)/(9^2)
= (25 x 25)/(9 x 9)
= 625/81
= 7 58/81
25.25=625
9.9=81
625/81=7 58/81
(81 into 7=567
567+58=625)
LOL....
25*25/(9*9)
=625/81
= 7 58/81
square both 25 and 9
you get 625/81
reduce that and you get 7 58/81
you square both 25 and 9
but keep the fraction
25²/9²
= 625/81 = 7 58/81
put it into a calculator and press the square button
