Answer: $\bold{-7+2\sqrt{14}+5\sqrt{7}-10\sqrt{2}}$

Step-by-step explanation:

$\dfrac{\sqrt7-5}{\sqrt7+\sqrt8}\bigg(\dfrac{\sqrt7-\sqrt8}{\sqrt7-\sqrt8}\bigg)=\dfrac{7-2\sqrt{14}-5\sqrt{7}+10\sqrt2}{7-8}=\dfrac{7-2\sqrt{14}-5\sqrt{7}+10\sqrt2}{-1}\\\\\\=\boxed{-7+2\sqrt{14}+5\sqrt{7}-10\sqrt2}$

Simplify 4n5 + 3.5n5 + (-2.1n5). 4.4 n5 5.4 n5 20 n5 6.4 n5

ella [17]

Answer:

$4 {n}^{5} + 3.5 {n}^{5} + ( - 2.1 {n}^{5} )$

first create a bracket:

$= ( {4n}^{5} + 3.5 {n}^{5} ) + ( - 2.1 {n}^{5} )$

then solve the first bracket:

$= {7.5 {n}^{5} } + ( - 2.1 {n}^{5} )$

then open the remaining bracket:

$= {7.5n}^{5} - {2.1n}^{5}$

carryout the subtraction operation:

$= (7.5 - 2.1) {n}^{5} \\ { \boxed{ = {5.4n}^{5} }}$
