Question

1. (x-5)(2x + 3)
2. (3x)^4
3. (2x^2y)^3
4. (x+4)^2
5. (2x - 3)^2

Answer 1

1.(x-5)(2x+3)=2x^2-7x-15 2.(3x)^4=(3x)(3x)(3x)(3x) =9x^2(3x)(3x) =27x^3(3x) =81x^4 4.(x+4)^2=(x+4)(x+4) =x^2+8x+16 5.(2x-3)^2=(2x-3)(2x-3) =4x2-12x+9

Answer 2

1)
= (x-5)(2x+3)
= 2x² +3x -10x -15
= 2x² -7x -15

2)
= (3x)⁴
= 3⁴x⁴
= 81x⁴

3)
#Asumsi 1
= (2x²y)³
= (2³x^[2×3])(y³)
= 8y³x^6

#Asumsi 2
= (2x^[2y])³
= 2³x^[6y]
= 8x^[6y]

4)
= (x+4)²
= (x+4)(x+4)
= x² +4x +4x +16
= x² +8x +16

5)
= (2x-3)²
= (2x-3)(2x-3)
= 4x² -6x -6x +9
= 4x² -12x +9
