A rectangle has length of 14x^4 and a width of 7x^3. Find the area in square units.
14*7 x^4 x^3 = 98x^7
To find the area of a rectangle, you simply multiply its length by its width. In this case, the length of the rectangle is 14x^4 and the width is 7x^3.
To find the area, you can multiply the length and width together:
Area = length * width
Area = 14x^4 * 7x^3
When multiplying variables with the same base (x in this case), you add their exponents:
Area = 14 * 7 * (x^4 * x^3)
Area = 98 * x^(4 + 3)
Area = 98x^7
So, the area of the rectangle is 98x^7 square units.
