Q. a−3a0a2a−5⋅(a3a2)−4=axWhat is the value of x ?
Simplify Numerator: We will simplify the expression step by step using the properties of exponents.First, we simplify the numerator and the denominator separately.a2a−5 simplifies to a2−5 by using the property aman=am+n.
Simplify Denominator: Now we simplify a2−5 which equals a−3.
Divide Numerator by Denominator: Next, we simplify the denominator a−3a0. Since any number to the power of 0 is 1, a0=1. So, we have a−3⋅1 which is just a−3.
Simplify Second Part: Now we divide the simplified numerator by the simplified denominator. a−3/a−3 equals a−3−(−3) by using the property am/an=am−n.
Raise to Power: Simplifying a(−3−(−3)) gives us a0, because −3−(−3) equals 0.Since any number to the power of 0 is 1, a0=1.
Multiply Results: Now we need to simplify the second part of the expression ((a2)/(a3))−4. First, we simplify inside the parentheses: a2/a3 equals a2−3 by using the property am/an=am−n.
Final Simplification: Simplifying a2−3 gives us a−1.
Final Simplification: Simplifying a(2−3) gives us a−1.Now we raise a−1 to the power of −4, which is (a−1)−4. Using the property (am)n=am∗n, we get a(−1∗−4).
Final Simplification: Simplifying a(2−3) gives us a−1.Now we raise a−1 to the power of −4, which is (a−1)−4. Using the property (am)n=am∗n, we get a(−1∗−4).Simplifying a(−1∗−4) gives us a4.
Final Simplification: Simplifying a(2−3) gives us a−1.Now we raise a−1 to the power of −4, which is (a−1)−4. Using the property (am)n=am∗n, we get a(−1∗−4).Simplifying a(−1∗−4) gives us a4.Now we multiply the result from the first part of the expression, which is 1, by the result from the second part of the expression, which is a4. a−11 equals a4.
Final Simplification: Simplifying a(2−3) gives us a−1.Now we raise a−1 to the power of −4, which is (a−1)−4. Using the property (am)n=am∗n, we get a(−1∗−4). Simplifying a(−1∗−4) gives us a4. Now we multiply the result from the first part of the expression, which is 1, by the result from the second part of the expression, which is a4. a−11 equals a4. We have now simplified the entire expression to a4, which means that a−14. Therefore, the value of a−15 is a−16.
