The Deep Dive
First, let's break it down! You can simplify the expression by dividing the coefficients and the variables separately. The coefficients \(14\) and \(4\) can be simplified to \(3.5\) (or simply divide them as \(14 \div 4 = 3.5\)), and for the variables, you subtract the exponents. So for \(a^3\) divided by \(a\) (or \(a^1\)), you get \(a^{3-1} = a^{2}\). And for \(b^4\) divided by \(b\) (or \(b^1\)), it becomes \(b^{4-1} = b^{3}\). Putting it all together, the simplified form is: \[ \frac{14 a^{3} b^{4}}{4 a b} = 3.5 a^{2} b^{3} \] But if you're looking for whole numbers, you can multiply everything by \(2\) to clear the fraction, yielding: \[ 7 a^{2} b^{3} \]
