Answer 1

Step-by-step explanation:

$Use\ a^n\cdot a^m=a^{n+m}\\\\\bold{6.}\\\\7^5\cdot7^6=7^{5+6}=7^{11}\\\\\bold{7.}\\\\6^a\cdot6^v=6^{a+v}\\==========================\\Use\ \dfrac{a^n}{a^m}=a^{n-m}\\\\\bold{8.}\\\\\dfrac{2^8}{2^7}=2^{8-7}=2^1=2\\\\\bold{9.}\\\\\dfrac{x^{56}}{x^{24}}=x^{56-24}=x^{32}$

$=======================\\\\\bold{10.}\\\\\text{The scientific notation:}\ a\cdot10^k,\ \text{where}\ 1\leq a$

$\bold{12.}\\\\(-8x)\cdot3x^2=(-8\cdot3)(x\cdot x^2)=-24x^{1+2}=-24x^3\\\\\bold{13.}\\\\(-11z)^0=1\\\\a^0=1\ \text{for all real numbers except 0}\\\\\bold{14.}\\\\Use\ a^{-n}=\dfrac{1}{a^n}\\\\14^{-4}=\dfrac{1}{14^4}$
