Math Problem Statement

[(a^2)^3 * b^3] ÷ (2b^2 / a)^2

Solution

Let's solve the problem step by step.

The expression given is: [(a2)3×b3](2b2a)2\frac{[(a^2)^3 \times b^3]}{\left( \frac{2b^2}{a} \right)^2}

Step 1: Simplify the Numerator

The numerator is (a2)3×b3(a^2)^3 \times b^3.

Using the power of a power rule, (am)n=amn(a^m)^n = a^{m \cdot n}: (a2)3=a23=a6(a^2)^3 = a^{2 \cdot 3} = a^6

So the numerator becomes: a6×b3a^6 \times b^3

Step 2: Simplify the Denominator

The denominator is (2b2a)2\left( \frac{2b^2}{a} \right)^2.

Applying the power rule to each term inside the parentheses: (2b2a)2=(2)2(b2)2(a)2=4b4a2\left( \frac{2b^2}{a} \right)^2 = \frac{(2)^2 \cdot (b^2)^2}{(a)^2} = \frac{4b^4}{a^2}

Step 3: Rewrite the Expression

Now, we have: a6×b34b4a2\frac{a^6 \times b^3}{\frac{4b^4}{a^2}}

To simplify a fraction divided by another fraction, we can rewrite it as: a6×b3×a24b4=a6a2b34b4a^6 \times b^3 \times \frac{a^2}{4b^4} = \frac{a^6 \cdot a^2 \cdot b^3}{4b^4}

Step 4: Combine the Terms

Using the product of powers rule for aa and bb: a6a2=a6+2=a8a^6 \cdot a^2 = a^{6+2} = a^8 b3/b4=b34=b1=1bb^3 / b^4 = b^{3-4} = b^{-1} = \frac{1}{b}

So, the expression becomes: a84b\frac{a^8}{4b}

Final Answer

a84b\frac{a^8}{4b}
