Question

I need help working on radical expressions

Answer 1

Answer:

Step-by-step explanation:

1) 9√32 - √2

= 9*$\sqrt{2*16}$ - √2

= 9*4√2 - √2

= 35√2

2) √24 + √54

= $\sqrt{4*6}$ + $\sqrt{9*6}$

= 2√6 + 3√6

= 5√6

3) √12 - 6√3

= $\sqrt{4*3}$ - 6√3

=2√3 - 6√3

= -4√3

5) (4√3)

= $\sqrt{16*3}$

= √48

6) √32/√2

= $\sqrt{16*2} \sqrt{2}$

= $4\sqrt{2} *\sqrt{2}$

= 4*2

= 8

7) (3+√5)(2+√5)

= 6 + 3√5 + 2√5 + 5

= 11 + 5√5
