Question

Can x8 x y3 be written as a single power

Answer 1

$x^{8} *y^{3}$ can only be written as $x^{8}* y^{3}$ or as $x^{8} y^{3}$. One has the multiplication sign the other does not, which is why we put it together, because we know that if they are together they will be multiplied.

Answer 2

$x^{a}x^{b} =x^{a+b}\\ \\x^{8}x^{3}= x^{11}\\ \\Answer:\ x^{11}.$

$But\ x^{8}y^{3} \ cannot\ be\ simplified.$
