Question
Simplify. Assume that all exponents represent natural numbers.$\left(7 b^{4 n}-5 b^{2 n}+1\right)-\left(3 b^{3 n}-b^{2 n}\right)$
Step 1
First, let's distribute the negative sign to the terms inside the second parentheses: $7b^{4n} - 5b^{2n} + 1 - (3b^{3n} - b^{2n}) = 7b^{4n} - 5b^{2n} + 1 - 3b^{3n} + b^{2n}$ Now, let's combine like terms: Show more…
