What is the change of base formula for logarithms?

\( \begin{array}{l}\text { Ecuaciones Hultipicat } \\ \frac{9 x+3}{6}\end{array}=2 \)

Faktoriseer in Afrikaans \( 4(m-2 n)^{2}-25 \)

Use the Factor Theorem to determine whether \( x-2 \) is a factor of \( P(x)=x^{3}-3 x^{2}-4 x+ \) Specifically, evaluate \( P \) at the proper value, and then determine whether \( x-2 \) is a factor. \( \begin{array}{l}P(\square)=\square \\ x-2 \text { is a factor of } P(x) \\ x-2 \text { is not a factor of } P(x)\end{array} \)

Simplify the expression. Assume that the variable is unrestricted and use absolute value symbols when necessary. \[ \sqrt{25 y^{6}} \]

1.4 The straight line graph defined by \( y=2 x-4 \) will cut the \( y \)-axis at A. \( (0 ; 4) \) B. \( (-4 ; 2) \) C. \( (0 ;-4) \) D. \( (2 ;-4) \)
