Question

Laws of indices please solve

Answer 1

Answer:

here ,

$\sqrt[3]{x {}^{3} y {}^{3} }$

$= (x {}^{3} y {}^{3} ) {}^{ \frac{1}{3} }$

therefore the anwer is xy.

was it hellful plz let me know..

Answer 2

Answer:

xy

Solution,

$\sqrt[3]{ {x}^{3} {y}^{3} } \\ = {x}^{ \frac{3}{3} } {y}^{ \frac{3}{3} } \\ = xy$

It is a root law of indices.

For example:

$\: if \: {a}^{ \frac{m}{n} }$

is an algebraic term, where m and n are the positive integers, then :

${a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} }$

Hope this helps...

Good luck on your assignment...
