Step-by-step explanation:
We are looking for possible values of n in
5 < √n < 6, where n is a whole number.
(5)² < (√n)² < (6)² is allowed as all are positive.
25 < n < 36
Therefore there are 36 - 25 - 1 = 10 values for n.
Answer:
Answer:b and e
Step-by-step explanation:because b is (7x200)-(7x2) which =1386
1400 - 14 =1386 which is 7x198=1386
e because (7x100)+(7x90)+(7x8)
700 + 630 + 56 = 1386
true
