Answer:

#(x^2y^3w)/(t^4z^6)#

Explanation:

Using the #color(blue)"law of exponents"#

#color(orange)"Reminder " color(red)(|bar(ul(color(white)(a/a)color(black)(a^-m=1/a^m)color(white)(a/a)|)))#

We can now write the expression as

#x^2/1xxy^3/1xx1/t^4xx1/z^6xxw/1#

#=(x^2xxy^3xx1xx1xxw)/(1xx1xxt^4xxz^6xx1)=(x^2y^3w)/(t^4z^6)#
