Question

anonymous · Answer

7w^6x^34 sqrt(2)

anonymous · Answer

when your square rooting letters, if their exponents are even just divide by 2, if they are odd divide by 2 but leave the remainder of 1 underneath...... ex: sqrt(x^15) = x^7 sqrt(x^1)   ...... ex #2 sqrt(y3h19), y^1h^9 sqrt(y^1h^1)
