Answer:

x =±7

Step-by-step explanation:

3x²+5=152

To find x, subtract 5 from each side

3x²+5-5=152-5

3x²=147

Divide each side by 3

3x²/3=147/3

x²=49

Take the square root of each side

$\sqrt{x^{2} }=\sqrt{49}$

x =±7

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,

$\sqrt{50}$

$=\sqrt{25\times 2}$

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

$=5\sqrt{2}$
