Q. What is the value of A when we rewrite (532)−2x as Ax ?Choose 1 answer:(A) A=−564B A=21(C) A=(325)−2(D) A=(532)−2
Identify Base A: We need to express (532)−2x in the form of Ax. To do this, we will find a base A such that Ax is equivalent to (532)−2x.
Focus on (532):</b>First,let′sfocusonthebaseoftheexponent,whichis$(532). We want to find A such that Ax=(532)−2x. To do this, we need to find a base that, when raised to the power of x, gives the same result as (532) raised to the power of −2x.
Rewrite as (32/5)−2: We can rewrite (532)−2x as (532)−2^x by using the property of exponents that states (bm)n=bmn. This means we are looking for A such that A=(532)−2.
Calculate (32/5)−2: Now, let's calculate ((32)/(5))−2. This is the same as (5/32)2 because a negative exponent indicates reciprocal, and then we square the result.
Compare with Answer Choices: Calculating (325)2 gives us (52)/(322)=102425. This is the value of A.
Compare with Answer Choices: Calculating (5/32)2 gives us (52)/(322)=25/1024. This is the value of A.Now we compare the value of A we found with the answer choices. The value of A is 25/1024, which is not listed in the answer choices directly. However, we can see that this is equivalent to ((5)/(32))2, which is the reciprocal of the base raised to the power of −2. Therefore, the correct answer choice is (C)A=((5)/(32))(−2).
