  1. 75=253=253=53the square root of 75 end-root equals the square root of 25 center dot 3 end-root equals the square root of 25 end-root center dot the square root of 3 end-root equals 5 the square root of 3 end-root 56180=56365=5665=55five-sixths the square root of 180 end-root equals five-sixths the square root of 36 center dot 5 end-root equals five-sixths center dot 6 center dot the square root of 5 end-root equals 5 the square root of 5 end-root 7a1036=a10736=|a5|76the square root of the fraction with numerator 7 a to the tenth power and denominator 36 end-fraction end-root equals the fraction with numerator the square root of a to the tenth power end-root center dot the square root of 7 end-root and denominator the square root of 36 end-root end-fraction equals the fraction with numerator the absolute value of bold a to the fifth power end-absolute-value the square root of 7 end-root and denominator 6 end-fraction

️ Шаг 2: Внесение множителя под знак корня

  1. 46=426=166=964 the square root of 6 end-root equals the square root of 4 squared center dot 6 end-root equals the square root of 16 center dot 6 end-root equals the square root of 96 end-root 16108=136108=10836=3one-sixth the square root of 108 end-root equals the square root of 1 over 36 end-fraction center dot 108 end-root equals the square root of 108 over 36 end-fraction end-root equals the square root of 3 end-root a35a cubed the square root of 5 end-root :
    • Если a0a is greater than or equal to 0, то a35=(a3)25=5a6a cubed the square root of 5 end-root equals the square root of open paren a cubed close paren squared center dot 5 end-root equals the square root of 5 bold a to the sixth power end-root Если a<0a is less than 0, то a35=(a3)25=5a6a cubed the square root of 5 end-root equals negative the square root of open paren a cubed close paren squared center dot 5 end-root equals negative the square root of 5 bold a to the sixth power end-root

️ Шаг 3: Сравнение значений Для сравнения 17the square root of 17 end-root и 9189 the square root of one-eighth end-root внесем множитель под знак корня во втором выражении:

  1. 918=9218=818=10.1259 the square root of one-eighth end-root equals the square root of 9 squared center dot one-eighth end-root equals the square root of 81 over 8 end-fraction end-root equals the square root of 10.125 end-root Сравниваем подкоренные выражения: 17>10.12517 is greater than 10.125 Следовательно, 17>918the square root of 17 end-root is greater than 9 the square root of one-eighth end-root

Ответ:

  1. 535 the square root of 3 end-root ; 555 the square root of 5 end-root ; |a5|76the fraction with numerator the absolute value of a to the fifth power end-absolute-value the square root of 7 end-root and denominator 6 end-fraction 96the square root of 96 end-root ; 3the square root of 3 end-root ; sign(a)5a6sign open paren a close paren the square root of 5 a to the sixth power end-root 17>918the square root of 17 end-root is greater than 9 the square root of one-eighth end-root

Нужно ли упростить полученные выражения дальше или перейти к другим задачам с радикалами?
