Use the properties of exponents to simplify the expression: \( \left(a^{6}\right)^{2} a^{7} \) a.) \( a^{19} \) b.) \( a^{15} \) c.) \( a^{84} \) d.) \( a^{56} \)

Type the correct answer in the box. Use numerals instead of words. If necessary, use/ for the fraction bar What value of \( x \) satisfies this equation? \( 1.5(4)^{2 x}=12 \) Round your answer to the nearest hundredth. The value of \( x \) is

What is the solution to the equation? \( \sqrt{x}+6=x \)

Enter the correct answer in the box. Rewrite the expression \( 2 \sqrt[4]{x^{7}} \) using rational exponents. \( \begin{array}{lll}\frac{\square}{\square} & \text { (ㅁ) } \mid \text { 미 } \square^{\square} \mid+--\end{array} \)

uisl 3 a) \( x^{2}-12=0 \) b) \( 4 x^{2}-7 x=0 \) c) \( 6 x+12 x^{2}=0 \)

b) \( -x^{2}+x+72=0 \)
