كتابة المقدار الجبري في أبسط صورة

أجد ناتج ضرب كل مما يأتي في أبسط صورة:

(1) 2x(x – 4)

begin mathsize 20px style 2 x left parenthesis x minus 4 right parenthesis equals 2 x squared minus 8 x end style

(2) (x + 4)(x – 5)

begin mathsize 20px style left parenthesis x plus 4 right parenthesis left parenthesis x minus 5 right parenthesis equals x squared minus 5 x plus 4 x minus 20 equals x squared minus x minus 20 end style

(3) (3x + 1)2

begin mathsize 20px style left parenthesis 3 x plus 1 right parenthesis squared equals 9 x squared plus 6 x plus 1 end style

 

التحويل من الصيغة الجذرية إلى الصيغة الأسيّة

أحوّل كلاً مما يأتي من الصيغة الجذرية إلى الصيغة الأسيّة:

(4) begin mathsize 20px style fifth root of x to the power of 4 end root end style

begin mathsize 20px style fifth root of x to the power of 4 end root equals x to the power of 4 over 5 end exponent end style

(5) begin mathsize 20px style cube root of x end style

begin mathsize 20px style cube root of x equals x to the power of 1 third end exponent end style

(6) begin mathsize 20px style square root of x minus 1 end root end style

begin mathsize 20px style square root of x minus 1 end root equals left parenthesis x minus 1 right parenthesis to the power of 1 half end exponent end style

(7) begin mathsize 20px style fraction numerator 5 over denominator root index 7 of x to the power of 4 end root end fraction end style

begin mathsize 20px style fraction numerator 5 over denominator root index 7 of x to the power of 4 end root end fraction equals 5 over x to the power of 4 over 7 end exponent equals 5 x to the power of negative 4 over 7 end exponent end style
