How do you convert numbers/fractions with exponents or roots into decimals?

Question

how do you convert scientific notation into a decimal?

Answer 1

6^3 = 6*6*6
4^2 = 4*4
10^4 = 10*10*10*10


(a/b)^n = (a^n)/(b^n)
(3/2)^2 = (3^2)/(2^2) = 9/4 = 2.25


With roots you have to use a calculator.

Answer 2

customarily, you may no longer. i will write sqrt(a million.40 4) as a million.2, yet for many numbers, you may in basic terms approximate the respond. 7 x sqrt(10) is approximately 22.14, yet there is not any top decimal answer.

Answer 3

you can use your calculator. if you don't have one , you can use approximation method by trying the neighbouring number and taking the average of the resulting answer each time but it will be time consuming
