can you guys give a answer..?

1.(5x) (3x)=?
2.(9y) (-4y)=?
3.(6ab) (-10ab)=?
4.(7m) (-3m) (-10m)=?
5.(-3k) (-2k5) (-k8)=?

Sagot :

Multiply the integers as usual... and add the exponents at the variables...

For no. 1:
(5x)(3x) = 15x²

For no. 2:
(9y)(-4y) = -36y²

For no. 3:
(6ab)(-10ab) = -60a²b²

For no. 4:
(7m)(-3m)(-10m) = 210m³

For no. 5:
(-3k)(-2k⁵)(-k⁸) = -6k¹⁴
