Question

multiply:2 4√3 by 5 4√81

Answer 1

Hello!
Here is your answer

$\sqrt[4]{81} = \sqrt[4]{3 {}^{4} } = 3$
$5 \times \sqrt[4]{81} = 5 \times 3 = 15$
$2 \sqrt[4]{3} \times 15 = 30 \sqrt[4]{3}$

Answer 2

Answer:

Step-by-step explanation:

Concept:

Definition of multiplication:

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiplication is essentially the process of repeatedly adding sets of identically sized objects.

Definition of square root:

A value that, when multiplied by itself, yields the number is the square root of a number.

Definition of root and power:

Multiply the base, represented by the letter a, or the exponent, represented by the letter b, to determine the power of a given integer. The cubed root of a number is obtained by multiplying it by itself three times, while the square root of a number x  is obtained by multiplying it by itself twice.

Given:

$2 \sqrt[4]{3} by 5 \sqrt[4]{81}$

Find:

$multiply 2 \sqrt[4]{3} by 5 \sqrt[4]{81}$

Solution:

given $2\sqrt[4]{3} by5\sqrt[4]{81}$

$\sqrt[4]{81} =\sqrt[4]{3^4 }$

       $=3$

$5\sqrt[4]{81} =5*3$

         $=15$

$2\sqrt[4]{3} *5\sqrt[4]{81} =2\sqrt[4]{3} *15$

                   $=30\sqrt[4]{3}$
