Question

Simplify below these questions

rule: little x means times not the other way round
A: 3X^2Y^4 x 2X^6Y
B: XZ^3 x 4X^4Z^5
C: 4A^3^2 x 3A^6B^5
D: 6S^5T x S^4T^2

Answer 1

A:
`3x^2y^4\cdot2x^6y=6x^8y^5`

B:
`xz^3\cdot4x^4z^5=4x^5z^8`

C:
`4a^3^2\cdot 3a^6b^5=12a^(15)b^5`

D:
`6s^(5t)\cdot s^(4t)^2=6s^(16t^2+5t)`

There was some ambiguity you posed with such exponents but I assumed strictly.

Hope this helps.
