simplify the following 4√625-3 3√1728+5√625-3 3√27. plzzzz answer fast I will follow u​

Answer 1

Answer:

The question is solved above

Answer 2

$\red{ Simplify \: \sqrt[4] {625} - 3 \times \sqrt[3] {1728} + 5 \times \sqrt{625} - 3 \times \sqrt[3] {27} }$

$i) \sqrt[4] {625} \\= \sqrt[4] { 5^{4}} \\= 5^{\frac{4}{4}} \\= 5$

$ii) \sqrt[3] { 1728} \\= \sqrt[3] { 12^{3}} \\= 12^{\frac{3}{3}} \\= 12$

$iii ) \sqrt{625} \\=\sqrt{25^{2}} \\= 25$

$iv ) \sqrt[3] {27} \\= \sqrt[3] {3^{3}} \\= 3^{\frac{3}{3}} \\= 3$

$Now , \sqrt[4] {625} - 3 \times \sqrt[3] {1728} + 5 \times \sqrt{625} - 3 \times \sqrt[3] {27}$

$= 5 - 3 \times 13 + 5 \times 25 - 3 \times 3 \\= 5 - 39 + 125 - 9 \\= 82$

Therefore.,

$\red{ Simplify \: \sqrt[4] {625} - 3 \times \sqrt[3] {1728} + 5 \times \sqrt{625} - 3 \times \sqrt[3] {27} }$

$\green {= 82}$
