An estimate for negative square root of 93 is ____.
[-(sqrt(93))] If its an imaginary just apply absolute value

Find perfect squares close to 93.
9^2 = 81
10^2 = 100

Find the difference between the squares and 93. (The smaller the value the closer it is to the root of the square.)
100 - 93 = 7
93 - 81 = 12

So, the first answer is D.) -9.5

Test taking strategy: Use the answer options and square them.
9.1 * 9.1 ~= 82
9.5 * 9.5 ~= 90

A Square's Area is the length of one side multiplied by itself. This problem has the same approach given for the first question.

Find perfect squares close to 52.
7^2 = 7*7 = 49
8^2 = 8*8 = 64

Find the differences. (Smaller is better)(Make sure the differences are positive numbers.)
53 - 49 = 4
64 - 53 = 11

So 7FT is closer.

Here is a table for x^2.

SQUARES
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
7^2 = 49
8^8 = 64
9^2 = 81

1. C
2. B
3. D
4. B
