Question

A-81b Разделить /a-9/b /-Это корень

Answer 1

$\frac{ a-81b }{ \sqrt{a}-9 \sqrt{b} } = \frac{(\sqrt{a}-9 \sqrt{b} )(\sqrt{a}+9 \sqrt{b} )}{\sqrt{a}-9 \sqrt{b} } =\sqrt{a}+ \\ 9 \sqrt{b}$

Answer 2

Problem Statement

The problem is to divide the expression A-81b by /a-9/b and determine if it is a root.

Solution

To divide the expression A-81b by /a-9/b, we can use the division operator (/) in mathematics. The expression can be written as (A-81b) / (/a-9/b).

To determine if this expression is a root, we need more information about the variables and their values. Without this information, we cannot determine if the expression is a root or not.

Please provide more details or specific values for the variables A, a, and b so that we can solve the problem accurately.
