Answer:
22
Step-by-step explanation:
198 = 2×3²×11
For 198n to be a perfect square, each prime factor must have an even exponent. So the smallest 198n would be:
198n = 2²×3²×11²
198n = 4356
n = 22
Five hundred and sixty two divided by seven would be,
=80.28
53,278 can be written as:
50,000 + 3,000 + 200 + 70 + 8
