PLEASE ITS URGENT

Answer 1

4√16=2
6³√343=6×7
+18
5√243=3
√196=14

4√16-6³√343+18 5√243-√196
=
$2 - 6 \times 7 + 18 \times 3 - 14 = 0$

Answer 2

Answer:

Given : $\sqrt[4]{16} -6\sqrt[3]{343} + 18 \sqrt[5]{243} -\sqrt{196}$

To Find: Simplify

Solution:

$\sqrt[4]{16} -6\sqrt[3]{343} + 18 \sqrt[5]{243} -\sqrt{196}$

$(16)^{\frac{1}{4}} -6(343)^{\frac{1}{3}}+ 18 (243)^{\frac{1}{5}} -(196)^{\frac{1}{2}}$

$(2^{4})^{\frac{1}{4}} -6(7^{3})^{\frac{1}{3}}+ 18 (3^{5})^{\frac{1}{5}} -(14^2)^{\frac{1}{2}}$

$2 -6(7)+ 18 (3) -14$

$2 -42+ 54-14$

$0$

Hence $\sqrt[4]{16} -6\sqrt[3]{343} + 18 \sqrt[5]{243} -\sqrt{196} =0$
