Answer:

  • a) 25

  • b) 64

Step-by-step explanation:

In the question we're given value of x that is. 5 . And we have asked to find the value of x² and ( x + 3 )² . So we can find our answer by putting values of x in part a and b and after putting value we can solve them easily .

Solution : -

a) x²

Substituting value of x :

[tex] \longmapsto \: (5) {}^{2} [/tex]

[tex] \longmapsto \: \red{ \boxed{\bold{25}}}[/tex]

  • Therefore , value of x² is 25

b ) ( x + 3 )²

Substituting value of x :

[tex]\longmapsto \: (5 + 3) {}^{2} [/tex]

Adding 5 and 3 :

[tex]\longmapsto \: 8 {}^{2} [/tex]

[tex]\longmapsto \: \red{ \boxed{\bold{64}}}[/tex]

  • Therefore , value of ( x + 3 )² is 64
