Question

simplify the expression: (4x^3y^4z^5)(5x^4y^5z^3)

Answer 1

20x^7y^9z^8

Answer 2

\[\large (4x^3y^4z^5)(5x^4y^5z^3) \implies (4 \times 5)(x^3 \times x^4)(y^4 \times y^5) (z^5 \times z^3)\]

Answer 3

And remember in Multiplication bases are same then we add their exponents..

\[\large \color{green}{x^a \times x^b = x^{a+b}}\]

Answer 4

@ghass1978 you can't just directly answer the question

Answer 5

20 z^8 y^9 x^7

Answer 6

multiply x^3 and 4 then x^3 by 1 answer is x^3 out
then 4*x^3 and multply y^4 and 4x^3 and multiply y^4 and x^3
y^4 and x^3
then 4* x^3 * x^4
then z^5 * 4 y^4 * x^3
now we have 4* x^3 * y^4 * z^5
Multiply the exponent of y by y^5
Multiply the exponent of x by x^4
then 5 * x^4
you get 5*x^4*y^5
Multiply 4z^5*y^4*x^3 and 5*Z3*y^5*x^4
simplify and you will get z^8 y^9 x^7
4*5 is 20 so

20 z^8 y^9 x^7 Ans
