How to simplify using index laws
WebThe index laws apply to fractional indices as well as positive and negative integer indices. Using the first index law we know that 3 × 3 = 31 = 3 That is 3 multiplied by itself equals 3. The square root of 3, √3 is also a number that, when multiplied by itself, equals 3: √√3 × 3 = 3 √Since √3 behaves like 3 we say that 3 WebIndex Laws Mathematics IMA Intro. to Fin.

WebSimplify the cube root of 125 x to the sixth y to the third power. So taking the cube root of something is the same thing as raising that something to the 1/3 power. So this is equal to 125 x to the sixth y to the third power raised to the 1/3 power. And if we take a product of a bunch of stuff and raise that to the 1/3 power, that's the same ...
