To calculate 52, we multiply 5 by itself:
52=5×5=25
Thus, the answer is 25.
(ii) $rac{\sqrt{64}}{...........}$

To find rac{\sqrt{64}}{...........}, first calculate sqrt64:
64=8
Assuming this part refers to finding the missing value, we can denote it as x. Therefore, we need to express the answer in terms of x.
Work out $2^3 \times \sqrt{49}$.

To solve this, we calculate each part:
-
Calculate 23:
23=2×2×2=8
-
Next, calculate sqrt49:
49=7
Now we combine the results:
8×7=56
Thus, the answer is 56.
