If y > 0, which of the following is equal to sq.48y^3
Answer:
(A) 4y sq. rt. 3y
sqrt(48 * y^3)
= sqrt(16 * 3 * y ^2 * y)
= sqrt(16) * sqrt(3) * sqrt(y ^2) * sqrt(y)
= 4 * sqrt(3) * y * sqrt(y)
= 4y sqrt(3*y)
Answer:
(A) 4y sq. rt. 3y
sqrt(48 * y^3)
= sqrt(16 * 3 * y ^2 * y)
= sqrt(16) * sqrt(3) * sqrt(y ^2) * sqrt(y)
= 4 * sqrt(3) * y * sqrt(y)
= 4y sqrt(3*y)
