Answer:

\sqrt{16 \times9 \times 3  \:   \: equals \:4 \times 3 \times  \sqrt{3that \: eauas \: 12 \sqrt{3} } }

Step-by-step explanation:

Square root of 16 ×9×3= square root of 432

square root of 16 =4

square root of 9 =3

That will equal 4×3× square root of 3 which finally equals to 12 square root of 3.

Answer: 12\sqrt{3}

On a keyboard, you would write 12*sqrt(3)

==============================================

Explanation:

Find the prime factorization of 432 to get

432 = 2^4*3^3

That allows us to do the following steps

\sqrt{432} = \sqrt{2^4*3^3}\\\\\sqrt{432} = \sqrt{2^2*2^2*3^2*3^1}\\\\\sqrt{432} = \sqrt{2^2}*\sqrt{2^2}*\sqrt{3^2}*\sqrt{3^1}\\\\\sqrt{432} = 2*2*3*\sqrt{3}\\\\\sqrt{432} = 12\sqrt{3}\\\\

------------------

Or you could do something like this

\sqrt{432} = \sqrt{144*3}\\\\\sqrt{432} = \sqrt{144}*\sqrt{3}\\\\\sqrt{432} = 12\sqrt{3}\\\\

What are expressions? Help
slavikrds [6]

Answer:

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Step-by-step explanation:

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations, and other aspects of logical syntax. Many authors distinguish an expression from a formula, the former denoting a mathematical object, and the latter denoting a statement about mathematical objects.
