Question 12

Determine whether the statement below is true for positive real numbers a.
|a + 8| = |a| + 8

Accepted Answer

|a + 8| is the distance from a + 8 to 0 on the number line, and |a| + 8 is the distance from a to 0 plus 8. Since a is positive, a + 8 is greater than a, so |a + 8| is greater than |a|. Therefore, |a + 8| = |a| + 8.

Question 13

Simplify the expression. 
A) 
B) 
C) 
D) 
E)

Accepted Answer

The expression has hexadecimal numbers separated by underscores. The question asks to simplify the expression, so we need to convert the third number from the end, "b13d," to its successive value in hexadecimal. The value "b13d" is equal to 45309 in base 10, so we add 1 to get 45310, which is "b13e" in hexadecimal. Therefore, the simplified expression is 11eb12b0_aa86_b140_b394_a918e4c068cf_TB7866_11.

Question 18

Simplify the expression.(Assume that r, s, and t are positive.) 
A) 
B) 
C) 
D) 
E)

Accepted Answer

The given expression can be simplified using the rule of exponents: 
(a^m)^(n) = a^(m*n)

Therefore,

((r^4)^(s^2) / (t^3)^(rs))^(1/2)

= ((r^(4*s^2)) / (t^(3*rs)))^(1/2)

= (r^(2*s^2) * t^(-3rs/2))

= 11eb12b0_aa85_0350_b394_8b2fd2ceb75d_TB7866_11
