Answer:
II. Evaluate the following algebraic expressions for x= 3, y= -2, z= 1
substitute the value of x,y,and z
1. 2x + 3y -z 2. 3y² - 2x³ 3. x²y³ + 4z²
2(3) + 3(-2) - (1) 3(-2)² - 2(3)³ (3)²(-2)³ + 4(1)²
6 - 6 - 1 3(4) - 2(27) (9)(-8) + 4(1)
-1 12 - 54 -72 + 4
answer -1 -42 -68
answer -42 answer -68
4. 5xyz - 3x³y²z⁴
5(3)(-2)(1) - 3(3)³(-2)²(1)⁴
5(-6) - 3(27)(4)(1)
-30 - 81(4)
-30 - 324
-354
answer -354
III. Simplify or manipulate the given algebraic expressions. Show your Solution.
1. (-4x²) (5x⁴) 2. (x⁹/x²)² 3. (3s³t⁶) (6s²t⁸)
-4x² × 5x⁴ (x⁷)² 18s⁵t¹⁴
-20x⁶ x¹⁴
answer -20x⁶ answer x¹⁴ answer 18s⁵t¹⁴
4. (8x⁵/2x³) (6x³/3x⁵)
8/2x³ × 6x³/3
8/2 × 6/3
8/2 × 2
8
answer 8
