Question 60375
48x^3 under the radical sign + x (outside of radical) 147x under the radical sign
:
Assume you mean:
SqRt(48x^3) + x*SqRt(147x)
:
Factor to find the squares:
SqRt(16*3*x^2*x) + x*SqRt(49*3*x); 
:
Extract the squares and you have:
4x*SqRt(3x) + 7x*SqRt(3x)
:
We got SqRt(3) in both expressions so we can add them just like numbers:
4x*SqRt(3x) + 7x*SqRt(3x) = 11x*SqRt(3x)
:
Did this make sense to you??
