Question

pls answer this multiplication of polynomials. the sign of that * is in the nxt of exponent..
(10xy*5)(3x*3y)(-3X*4z*3)
whats the answer??/ plss

Answer 1

\[(10x y*5)(3x*3y)(-3x*4z*3)=-16200 x^3 y^2 z \]

Answer 2

how can u get that?

Answer 3

Gather like terms.
You can replace the inner parentheses combination ")(" with a "*".
(10*4*3*3*(-3)*4*3)*(x*x*x)*(y*y)*(z)
Starting from left to right:
(10*4*3*3*(-3)*4*3) = -16200
(x*x*x) = x^3
(y*y) = y^2
z = z

Does that help you?

Answer 4

if this sign * is the exponent sign you will get (-90x*(8)y*(6)z*(8) ) --- because when you multiply x*2 with x*3 the exponents you need to assumes and hence you will get x*5
- so hope that you have understood it

Answer 5

The ^ sign is the conventential exponent sign. * is the multiply sign and has the same meaning as the x sign.
