1. calcule:

a) 7ab + 4ab + 2ab =
b) 5cy² - 14cy² =
c) 0,5x³ + 2,4x³ - 1,6x³ =
d) (-6ab) • (-3a²b) =
e) a³m • 4a³m =
f) (80x⁴y²) + 10xy =
g) (150a⁶b⁵c³) + (25ab²c³) =
h) (2x³y)² =
i) (1,2ab²)³ =
j) (x²y + 5x²y¹ - 2x²y¹)² - (3x¹y¹ • 2x³y¹) =

Answer 1

a) 7ab + 4ab + 2ab = 13ab no vc e

b) 5cy² - 14cy² = -9cy²

c) 0,5x³ + 2,4x³ - 1,6x³ = 1,3x³

d) (-6ab) • (-3a²b) = +18a³b²

e) a³m • 4a³m = 4a⁶m²

f) (80x⁴y²) ÷ 10xy = 8x³y

g) (150a⁶b⁵c³) ÷ (25ab²c³) = 6a⁵b³

h) (2x³y)² = 4x⁶y²

i) (1,2ab²)³ = 1,728a³b⁶

j)(x²y + 5x²y¹ - 2x²y¹)²- (3x¹y¹ • 2x³y¹) =

(4x²y)²-(6x⁴y²)

16x⁵y²-6x²

10x³y²

❤️ Prontinho ❤️
