Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression (5/6b^2-1/5)^2. Expand \left(\frac{5}{6}b^2-\frac{1}{5}\right)^2. The power of a product is equal to the product of it's factors raised to the same power. Calculate the power \left(\frac{5}{6}\right)^2. Simplify \left(b^2\right)^2 using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 2 and n equals 2.
Expand the expression (5/6b^2-1/5)^2
Final answer to the exercise
$\frac{25}{36}b^{4}-\frac{1}{3}b^2+\frac{1}{25}$
