In liquid measure: 4 oz equals 1/2 cup. In dry measure: 4 oz (e.g. walnuts) equals 1 cup.
1 pound has 16 ounces so just multiply 16x4=64+6 ounces equals 70 ounces
16x4-81y4

64
80x4
16x4 is 64.
8x8 and 16x4
2x32
4 to the fourth power just means 4x4x4x4 and then the answer. So if you wanted to find the answer all you have to do is do 4x4 which is 16. Then 16x4 then find the answer. And then the answer to 16x4 times 4.
40 + 24 = 64
(2x - 3)(2x + 3)(4x2 + 9)
