Question

find the value of ✓100*✓144​

Answer 1

Answer:

Therefore, the answer is 120.

Step-by-step explanation:

Given the question is √100 × √144

We have to find the value of above expression.

Root 'a' , that is √a = $a^{\frac{1}{2} }$

We know that 10 square = 10 × 10 = 100

and 12 square = 12 × 12 = 144

Now the solution is

$\sqrt{100} *\sqrt{144} = (10^{2} )^{\frac{1}{2} } *(12^{2})^{\frac{1}{2} } \\ = 10*12\\ = 120$

Therefore, the answer is 120.
