Simplify the given expression. Assume that no variable equals 0. (14x20y10 / 28x12y14)4
liq [111]

Answer:

\frac{1}{2^{4}*14^{3} *x^{28}*y^{46}}

Step-by-step explanation:

To simplify the expression \frac{14x^{20}y^{10}}{(2*14*x^{12} y^{14} )^{4}} first we need to raise every member of the denominator to the given exponent, number 4

Remember that (x^{b} )^{c} =z^{b*c} where 'a' and 'b are natural numbers (any numbers you want

\frac{14x^{20}*y^{10}}{2^{4}*14^{4}*x^{48}*y^{56}}

Where we can make some operations, remember that \frac{x^{a} }{x^{c} }=x^{a-c}

\frac{1}{2^{4}*14^{3} *x^{28}*y^{46}}

We have assumed that nor x, nor y equals 0 in any moment, since if that would happen, we ca not simplify anything bacause error math 0/0.
