    (a - b) (a + b) = a2 - b2
    (5 - √5)(5 + √5) = 52 - √5 2
    = 25 - 5
    = 20

    Axiom 1: If a ray stands on a line, then the sum of two adjacent angles so formed is 180.

    Axiom 2: If the sum of two adjacent angles is 180°, then the non-common arms of the angles form a line.

    We have,
    {tex}\left(16^{-\frac{1}{5}}\right)^{\frac{5}{2}}{/tex} = {tex}16^{-\frac{1}{5} \times \frac{5}{2}}{/tex} [as (am​​​​​​)n= am×n ​​​​​​] 
    = {tex}16^{-\frac{1}{2}}{/tex}
    = {tex}\frac{1}{16^{\frac{1}{2}}}{/tex}
    = {tex}\frac{1}{\left(4^{2}\right)^{\frac{1}{2}}}{/tex}
    = {tex}\frac{1}{4}{/tex}.

    We write in short 'CPCT' for corresponding parts of congruent triangles.It is used in questions where you have already proven something but you need to prove it again . Ex-if you already proved congruency and you need to prove that 2 sides are congruent. You can easily use CPCT.

    Sangam Bishnoi 5 years, 3 months ago

    CPCT means Congruent Parts Of Congruent Triangle . It is used when you proved two triangle in case one . If you need re prove something ( like lines are equal and parallel , angle prove and so on ) in that two triangle then you write IT IS ALREADY PROVE BY CPCT
