Question

find the positive square root of the following:
i)√50+√48
ii)x+y+z+2√xy+zx

Answer 1

Step-by-step explanation:

1) √50 = √25×2 = 5√2

√48=√16×3=4√3

so (√50+√48)^1/2=(5√2+4√3) ^1/2

2)( x+y+2√xy+z+zx) ^1/2

=((√x)^2+(√y)^2+2(√x)(√y)+ zx+x) ^1/2

= ((√x+√y)^2+x(z+1)) ^1/2

see your answer
