Use rational exponents to simplity Vab20 Solution1 sqrtab20
Use rational exponents to simplity. V(ab)20
Solution
1) ( sqrt(ab))^20
sqrt is equivalent to raised to power 1/2
therefore , sqrt(ab)^20 = (ab)^20/2
on simplifying the exponents we get
(ab)^10
2) (sqrt (6mn))^5
= (6mn)^5/2
3) (4x^6)^5/2
= 4 ^ 5/2 * x^30/2
= (4^5/2)*(x^15)
4) 16^3/4
applying exponent property
a^m/n = nth root ( a^m )
therefore , 16^3/4 = 4th root ( 16^3)
5) (xy)^1/9
in radical form
= 9th root (xy)
