Question

Vă rog repede am nevoie urgentă ​

Answer 1

Răspuns:

a) 8x⁶:4x⁴=2x²

b)3xy • 8x²= 24x³y

c)16x⁴: 16x⁴

d)64x⁶y⁶:-8x³y⁵= -8x³y1

e)9a²b³ : 3ab²• -3ab=-9 a²b²

f)16x⁴:4x²:x²=4

Answer 2

$\it a)\ = (8x^5):(4x^4)=2x\\ \\ b)\ = 3xy\cdot16x^2=48x^3y\\ \\ c)\ = 16x^4:(16x^4)=1\\ \\ d)\ = (64x^6y^6):(-8x^3y^5)=-8x^3y\\ \\ e)\ = (3ab)\cdot(-3ab)=-9a^2b^2\\ \\ f)\ = (16x^4):(4x^2):x^2=(4x^2):x^2=4$
