WebThat is really saying to do a cube (3) and a square root (1/2), in any order. Let me explain. A fraction (like m/n) can be broken into two parts: a whole number part ( m) , and a fraction ( 1/n) part So, because m/n = m × (1/n) we can do this: x m/n = x (m × 1/n) = (x m) 1/n = n√xm The order does not matter, so it also works for m/n = (1/n) × m: WebThe cube root is a root of order 3. For Example: 8 has one cube root. The cube root of 8 is 2 because 2 3 = 8. −8 has one cube root. The cube root of −8 is −2 because (−2) 3 = −8. The fourth root is a root of order 4. For …

Compute without using a calculator. Explain how you know that your answer is 10 −2 correct. 10^-2 is equal to 0.01. This is because 10^2 is 100. Being that the exponent is now negative, you have to divide it instead of multiply it. So, you would work down the pattern and take 10^0 which is 1 then divide it by 100 to get the negative exponent. ctu cleveland
