Question

simplify: sqrt (16)/sqrt (4) + sqrt (2)

a) 8 - 2 sqrt (2)
b) 8 - sqrt (2) / 2
c) 2
d) 4 - 2 sqrt (2)

Answer 1

The answer is D.
The sqrt of 16 is 4. The sqrt of 4 is 2.And just keep the sqrt of (2) the same.(:

Answer 2

thanks beth :)

Answer 3

the way you typed it ...
sqrt (16)/sqrt (4) + sqrt (2)
= 4/2 + √2
= 2 + √2 which would be none of the anwers

If you meant
sqrt (16)/(sqrt (4) + sqrt (2))
= 4/(2 + √2)
= 4/(2 + √2) * (2-√2)/(2-√2)
= (8-4√2)/(4-2)
= 4 - 2√2

Beth by coincidence picked the right answer, but for all the wrong reasons
