To make it simple, just subtract the age that you died to the age that you were born.
1730 - 1620 = 110
Which means that you would die at the age of 110 if you were born at 1620 and died on 1730.
Your answer is 3 because all you do is form it in a fraction
Answer:
25
Step-by-step explanation:
This expression is easier than it looks like. I thought that to solve it you have for example to express the 2 via 10 * 5^-1 and stuff like that - but you can multiply and divide this expression by some factor. In our case first we multiply by conjunctive expression root(5-2root2) and the second by root(6+2root5). In first we get root16 and the second calculate.
The inequality is

write 7 as 7b/b to have all the expressions in common denominator:






here b=1 is a root and b=0 is not in the domain of the expression, but it still has an effect in the sign of the expression.
the sign table of

is :
+++++++[0] --------[1] +++++
this means that for values of b to the left of 0 and to the right of 1, the expression is positive, and for values of b in (0, 1), the expression is negative.
that is

for b∈(0, 1)
Answer: (0, 1)
