Which expression is equivalent to x3(2+y5)?(1 point)
Responses
2x3+y5
2 x cubed plus y superscript 5 baseline
2x3+x3y5
2 x cubed plus x cubed y superscript 5 baseline
x3+2+y5
x cubed plus 2 plus y superscript 5 baseline
x3+x3+xy+xy+xy
x cubed plus x cubed plus x y plus x y plus x y
The correct expression is:
2x3 + xy5
thats wrong
I apologize for the incorrect response. The correct expression is x3(2+y5) which simplifies to 2x3 + x3y5.
