Answer:
C) 8 and 9
Step-by-step explanation:
We know that 70 is between two perfect squares.
The square numbers 64 and 81 can help us solve this question.
64<70<81
We take square root to get:
We simplify this to get:
Therefore √70 is between 8 and 9.
The correct option is C.
8Z = 64
Divide both sides by 8.
8Z/8 = 64/8
Z = 64/8
Z = 8
Your final answer is B. 8.
The third one: No, yes, no
1st digit: 9 possibilities (can’t have 0)
2nd digit: 10 possibilities
3rd digit:10
4th digit:10
5th digit:10
6th digit: 4 possibilities (it can only be even)
9•10•10•10•10•4 =360,000 possibilities
