Answer:
She should buy 7 large pieces of fabric to make 7 scarves
Step-by-step explanation:
Length of side of each square piece = ![\frac{1}{4} yards](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20yards)
Area of 1 square piece = ![Side^2 = (\frac{1}{4})^2 = \frac{1}{16} yards^2](https://tex.z-dn.net/?f=Side%5E2%20%3D%20%28%5Cfrac%7B1%7D%7B4%7D%29%5E2%20%3D%20%5Cfrac%7B1%7D%7B16%7D%20yards%5E2)
Doris uses 8 square pieces to make one scarf.
Area of 8 square pieces = Area of 1 scarf = ![8 \times \frac{1}{16}=\frac{1}{2} yards^2](https://tex.z-dn.net/?f=8%20%5Ctimes%20%5Cfrac%7B1%7D%7B16%7D%3D%5Cfrac%7B1%7D%7B2%7D%20yards%5E2)
Area of 7 scarves = ![7 \times \frac{1}{2}=\frac{7}{2} yards^2](https://tex.z-dn.net/?f=7%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B7%7D%7B2%7D%20yards%5E2)
Length of fabric bought by Doris =![\frac{1}{4} yards](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20yards)
Breadth of fabric brought by Doris = 2 yards
Area of fabric brought by Doris = ![Length \times Breadth = \frac{1}{4} \times 2=\frac{1}{2} yards^2](https://tex.z-dn.net/?f=Length%20%5Ctimes%20Breadth%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20%5Ctimes%202%3D%5Cfrac%7B1%7D%7B2%7D%20yards%5E2)
So,She should buy no. of large pieces of fabric to make 7 scarves =![\frac{\frac{7}{2}}{\frac{1}{2}}=\frac{7}{2} \times 2 =7](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B7%7D%7B2%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B7%7D%7B2%7D%20%5Ctimes%202%20%3D7)
Hence She should buy 7 large pieces of fabric to make 7 scarves

Answer:
Step-by-step explanation:
You can't solve for the values of a and b because 6a³b²·2a⁴b³ is an expression, not an equation. However, you can simplify the expression:
6a³b²·2a⁴b³ = 6·2·a³⁺⁴b²⁺³ = 12a⁷b⁵
