When you see a radical, you want to ask yourself, "what number can multiply by itself to give the number under the radical?" [3] For instance, if you see √ (9), you want to find the number that can be squared to make nine. chip king morehead city

WebWe can "pull apart" multiplications under the root sign like this: n√ab= n√a× n√b (Note: if n is even then a and b must both be ≥ 0) This can help us simplify equations in algebra, and also make some calculations easier: Example: 3√128= 3√64×2= 3√64× 3√2= 43√2 So the cube root of 128 simplifies to 4 times the cube root of 2. WebMar 7, 2024 · used to indicate a root is called a radical and is therefore read "x radical n," or "the nth root of x." In the radical symbol, the horizontal line is called the vinculum, the quantity under the vinculum is called the radicand, and the quantity n written to the left is called the index. The special case x 2 is written x WebFeb 24, 2024 · When we look at the symbolic picture in there, we see that n n is the order of the root, so we input n = 18 n = 18. In turn, a a is the number under the radical, so we take a = 1.5597 a = 1.5597. This makes the root calculator spit out the answer to be: \small 1+\mathrm {interest\ rate} =1.025 1 + interest rate = 1.025. chip kindle download
