Q). The degree of (- 1/20 x⁴y³) × (- 5 x⁷y²) is

kap26 [50]

Step-by-step explanation:

$\large\underline{\sf{Given \:Question - }}$

The degree of

$\rm :\longmapsto\:\bigg( - \dfrac{1}{20} {x}^{4} {y}^{3}\bigg) \times \bigg( - 5 {x}^{7} {y}^{2} \bigg)$

$\green{\large\underline{\sf{Solution-}}}$

Given polynomial is

$\rm :\longmapsto\:\bigg( - \dfrac{1}{20} {x}^{4} {y}^{3}\bigg) \times \bigg( - 5 {x}^{7} {y}^{2} \bigg)$

can be regrouped as

$\rm \: = \: \bigg( - \dfrac{1}{20} \times ( - 5) \bigg) \times \bigg( {x}^{4} \times {x}^{7}\bigg) \times \bigg( {y}^{3} \times {y}^{2} \bigg)$

We know,

$\red{\rm :\longmapsto\:\boxed{\tt{ {x}^{m} \: \times \: {x}^{n} \: = \: {x}^{m \: + \: n} \: }}}$

So,

$\rm \: = \: \dfrac{1}{4} \times {x}^{4 + 7} \times {y}^{3 + 2}$

$\rm \: = \: \dfrac{1}{4} \times {x}^{11} \times {y}^{5}$

$\rm \: = \: \dfrac{ {x}^{11} \times {y}^{5} }{4}$

$\rm \: = \: \dfrac{ {x}^{11} \: {y}^{5} }{4}$

Thus,

$\rm :\longmapsto\:\boxed{\tt{ \bigg( - \dfrac{1}{20} {x}^{4} {y}^{3}\bigg) \times \bigg( - 5 {x}^{7} {y}^{2} \bigg) = \frac{ {x}^{11} \: {y}^{5} }{4} \: }}$

<em>So, Degree of polynomial expression is 16.</em>

Using the least common denominator rename 3/5 and 11/20?

irina1246 [14]

Answer:

12/20 and 11/20.

Step-by-step explanation:

The least common denominator between 3/5 and 11/20 is 20.

For the first equation, we multiple the numerator and denominator by 4 and we get 12/20.

The second equation already has a denominator of 11/20 so we can leave it as is.
