Answer:

2) \frac{\sqrt{77}}{11}

3) 5√2

Step-by-step explanation:

Simplest radical form of an expression is the expression in radical so that there are no more square roots, cube roots, 4th roots, etc left to find, after rationalising the denominator ( if needed ).

2. Here the given expressions,

\frac{\sqrt{7}}{\sqrt{11}}

For rationalising the denominator multiply both numerator and denominator by √11,

\frac{\sqrt{77}}{11}

3. given expression,

\sqrt{50}

=\sqrt{25\times 2}

=\sqrt{25}\times \sqrt{2}   (\because \sqrt{ab}=\sqrt{a}\sqrt{b})

=5\sqrt{2}

asambeis [7]

Answer:

Length =40 ft.

width. = 8 ft.

Step-by-step explanation:

If The length is five times the width , then

width = w

length = 5w

Perimeter of Rectangle = 2( l+b)

2(5w+w)= 96

2( 6w) = 96

12 w= 96

w = 96/12

w= 8ft.

length = 5(8)

= 40 ft
