Step-by-Step Solution

Answer

The value of Algebraic expressions for x=3 is

(a).9

(b).64

(c).40

Step 1. Given information

Given expressions are :

(a) x²

(b)4^x

(c)3x²+4x+1

We have to evaluate the given expression for x=3.

Part (a) Step 1.

Replace x with 3 :

3²

=9

The value of the expression is 9.

Part (b) Step 1

Evaluate the expression (b). 4^x for x=3

Replace x with 3 :

 4³

=64

The value of he expression is 64.

Part (c) Step 1

Evaluate the expression (c) 3x²+4x+1 for x=3

Replace x with 3:

 3(3)²+4(3)+1 

=27+12+1

=40

The value of the expression is 40.
