$3999991=4000000-9=2,000^2-3^2=(2000-3)(2000+3)=1997\cdot2003$

As we can see, the number 3999991 can be expressed as a product of two numbers that are not 1 and the number 3999991 itself, therefore that number is not prime.

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log( $\frac{x}{y}$ )

log $x^{n}$ ⇔ nlogx

Given

2(log18- log3) + $\frac{1}{2}$ log $\frac{1}{16}$

= 2(log( $\frac{18}{3}$ ) ) + log $(\frac{1}{16}) ^{\frac{1}{2} }$

= 2log6 + log $\frac{1}{4}$

= log6² + log $\frac{1}{4}$

= log36 + log $\frac{1}{4}$

= log( 36 × $\frac{1}{4}$ )

= log9

<h3>Answer:</h3><h3>D</h3><h3 /><h3>Step-by-step explanation:</h3><h3></h3><h3>In a function, an input (x) value should have only one output (y) value.</h3><h3 />
