Answer:

False

Step-by-step explanation:

Assuming a and b are 2 different terms,

Sqrt a + Sqrt b is not equal to Sqrt (a * b).

The only way to obtain Sqrt (a * b) is by doing the following:

Sqrt (a * b) = Sqrt (a) * Sqrt (b)

$x^2=\dfrac{121}{196}\iff x=\pm\sqrt{\dfrac{121}{196}}\\\\x=-\dfrac{\sqrt{121}}{\sqrt{196}}\ \vee\ x=\dfrac{\sqrt{121}}{\sqrt{196}}\\\\\boxed{x=-\dfrac{11}{14}\ \vee\ x=\dfrac{11}{14}}\\\\\sqrt{a}=b\iff b^2=a\\\\\sqrt{121}=11\ \text{because}\ 11^2=121\\\\\sqrt{196}=14\ \text{because}\ 14^2=196$
