Answer 2

Answer:

33.8624770794

Step-by-step explanation:

Let

a=$\sqrt{48}$

b=$\sqrt{72}$

c=$\sqrt{27}$

d=$\sqrt{2}$

Use a calculator to find the square root of 48, 72, 27, 2. After you find those, use a calculator again and multiply 7a, 2c, 3d:

$\sqrt{48}$=6.92820323028x7=48.4974226119

$\sqrt{72}$=8.48528137424

$\sqrt{27}$=5.19615242271x2=10.3923048454

$\sqrt{2}$=1.41421356237x3=4.24264068712

Then subtract and or add those answers using a calculator:

48.4974226119-8.48528137424-10.3923048454+4.24264068712 = 33.8624770794
