2)..........

Answer 2

Answer:

Step-by-step explanation:

$1.\;\;\;\;\;\;\;81x^2-64y^2=(9x)^2-(8y)^2=(9x+8y)(9x-8y)\\\\2.\;\;\;\;\;\;\;-\frac{3}{8}-\frac{5}{12}=-\frac{1}{4}(\frac{3}{2}+\frac{5}{3})=-\frac{1}{4}(\frac{9+10}{6})=-\frac{19}{24}\\\\3.\;\;\;\;\;\;\;\frac{\sqrt{144}}{\sqrt{256}}=\frac{12}{16}=\frac{3}{4}\\\\4.\;\;\;\;\;\;\;435.23=4.3523\times10^{-2}\\\\5.\;\;\;\;\;\;\;(1^0\times2^0\times3^0)={1\times1\times1}=1$
