Suppose x, y, and z are all rational numbers. Is LaTeX: \frac{z}{\sqrt{x^2-y^2}}z x 2 − y 2 a rational number? Explain your answer. Group of answer choices No; a quotient of rational numbers is not always rational. Yes; the square and square roots cancel out, leaving a rational number. There is not enough information to answer the question. No; the square root of any number is irrational.

x=0.2262943855

Step-by-step explanation:

Properties of exponents: 2^(x+1)=(2^x)(2^1)=2(2^x)

Properties of exponents: 3^(-x+1)=(3^-x)*(3^1)=(1/(3^x))*3=3/(3^x)

So:

2(2^x)=3/(3^x)

2(2^x)(3^x)=3

2(6^x)=3 (Remember that different bases w/ same exponents have their bases multiplied)

6^x=1.5

Take the base 6 logarithm: log6(6^x)=log6(1.5)

x=0.2262943855
