b) √4 − √49 + √25 =

c) 4√7 − 3√7

3 + 5√7

3 − 2√7

d) 3√50 + √18 − 2√8​

Answer 1

Respuesta:

a) =2$\sqrt{2}$

b) =0

c)= $\sqrt{7}$

d) =14$\sqrt{2}$

Explicación paso a paso:

a) =(3-5+2+2)($\sqrt{2}$)

=2$\sqrt{2}$

b) =2-7+5

=0

c) (4-3)*($\sqrt{7}$)

=1*$\sqrt{7}$

=$\sqrt{7}$

d) 3*$\sqrt{2*5*5}$+ $\sqrt{3*3*2}$ -2*$\sqrt{2*2*2}$

=3*5$\sqrt{2}$+ 3*$\sqrt{2}$-2*2$\sqrt{2}$

=15$\sqrt{2}$+3$\sqrt{2}$-4$\sqrt{2}$

=(15+3-4)*$\sqrt{2}$

=14$\sqrt{2}$
