Q. Simplify. Express your answer using exponents.(x1810x9)−5
Identify base and exponent: Identify the base and the exponent in the expression ((10x9)/(x18))−5.In ((10x9)/(x18))−5, the base is (10x9)/(x18) and the exponent is −5.
Simplify base by dividing powers: Simplify the base (10x9)/(x18) by dividing the powers of x. Using the quotient rule for exponents, xa/xb=xa−b, we get: (10x9)/(x18)=10/x18−9=10/x9
Apply negative exponent rule: Apply the negative exponent rule to the simplified base.The negative exponent rule states that (a/b)−n=(b/a)n. Applying this to our expression, we get:((10/x9))−5=(x9/10)5
Expand exponent over fraction: Expand the exponent over the fraction.Using the power of a quotient rule, (a/b)n=an/bn, we expand the exponent over the numerator and the denominator:(x9/10)5=x9∗5/105
Calculate powers of x and 10: Calculate the powers of x and 10. x9×5=x45105=100,000So, (x9/10)5=x45/100,000
