Answer:
210
Step-by-step explanation:
so the four Smallest Primes :
2, 3, 5, 7
When the number is Divided by 2, 3, 5 & 7 Leaves remainder 1
so N = 2a + 1
N = 3b + 1
N = 5c + 1
N = 7d + 1
-> N - 1 = 2a = 3b = 5c = 7d
N - 1 = 2 * 3 * 5 * 7
-> N - 1 = 210
-> N = 211
Next N - 1 = 2(210)
-> N - 1 = 420
-> N =421
Difference = 421 - 211 = 210
b
2.75 or 2
Answer:371.41
this is because you just need to carry the number over to the next place if the sum of the digits( example 8+9=17) if it is greater than 10
49
-3√(t) = -21
√(t) = 7
t = 49
