Question 274726: This question is in reference to adding and subtracting radical expressions:
2b SQRT^3(16b^2) + SQRT^3(128b^5) ANy help would be very much appreciated. Thank you
Sorry about weird writing of cubed squareroots, unsure how to write cubed square roots and square roots.

You can put this solution on YOUR website!
2b SQRT^3(16b^2) + SQRT^3(128b^5)
---------------------------------------------
Do you mean 2b(cube root of 16b^2) + (cube root of 128b^5)
-----
If so you get:
2b(2*cbrt(2b^2)) + 4b*cbrt(2b^2)
---
(4b + 4b)*cbrt(2b^2)
---
8b*cbrt(2b^2)
==========================
