Answer:
You use the powe of a product law of exponents to combine the exponents; this law says to add the exponents
Step-by-step explanation:
Volume = Length x width x Height
The given expression for the volume is:
Volume = (4x - 1)(x)(x³)
The product law of exponents states that "if we multiply two factors with the same base raised to an exponent together, their exponents can be added"
Note that x and x³ are of the same base, the their product will be x^(3+1), which will be x⁴
The volume will then become:
Volume = (4x - 1)x⁴
Distributing x⁴ over the expression, we have:
Volume = 4x⁵ - x⁴
Therefore, this makes sense because you use the powe of a product law of exponents to combine the exponents; this law says to add the exponents
