Question

Simplify
sqrt[(169)(x^6)(y^8)]

Answer 1

sqrt(169)=13 ----> sqrt[(169)(x^6)(y^8)] = 13*x^3*y^4

Answer 2

√(169*x^6*y^8)

13√(x^6*y^8)

in this case, it helps to think of the square root as an exponent (square root means to the 1/2 power)

13(x^6*y^8)^(1/2)

distribute the exponent

13(x^(6/2)*y^(8/2))

13*x^3*y^4

and don't forget the plus or minus sign

± 13*x^3*y^4
