Answer:
10^-99, 10^-17, 10^-5, 10^5, 10^14, 10^30
Step-by-step explanation:
Each root adds a exponent behind the initial one. The negatives add a decimal point and zeros in front
Explanation:
Consider the case a = -1. Then the expression becomes ...
(-1+1)(-1+1) > (-1-1)(-1-1) . . . . test case
0·0 > (-2)(-2) . . . . . simplified a bit
0 > 4 . . . . . . . . NOT TRUE
_____
If we subtract the right side from both sides, the inequality becomes ...
(a+1)(a+1) -(a-1)(a-1) > 0
a² +2a +1 -(a² -2a +1) > 0
4a > 0
a > 0
The inequality is only true for positive values of "a". For a ≤ 0, the inequality will not be true.
Answer:
216mm^2
Step-by-step explanation:
Area of a rectangle = length x width
