Question

write in the form 'nth root of a' (100)1.19​

Answer 1

Answer:

Even for perfect root numbers, a root can be difficult to calculate by hand. The most basic techniques involve trial and error.

Example – Find the fourth root of 4,096 using trial and error:

Try a number – 5 : 5 x 5 x 5 x 5 = 625 (too low)

Try another number that is more than 5 – 6 : 6 x 6 x 6 x 6 = 1,296 (too low)

Try a number that is more than 6 – 10 – 10 x 10 x 10 x 10 = 10,000 (too high)

Try a number in between 6 and 10 – 8 – 8 x 8 x 8 x 8 = 4,096 (answer)

Example 2 – Find the fifth root of 32,768 using trial and error:

Try a number – 5 : 5 x 5 x 5 x 5 x 5 = 3,125 (too low)

Try another number that is more than 5 – 6 : 6 x 6 x 6 x 6 x 6 = 7,776(too low)

Try a number that is more than 6 – 10 – 10 x 10 x 10 x 10 x 10 = 100,000 (too high)

Try a number in between 6 and 10 – 8 – 8 x 8 x 8 x 8 x 8 = 32,768 (answer)
