Answer 1

Answer:

Step-by-step explanation:

Step 1: Find the prime factors of 729

729 = 3 × 3 × 3 × 3 × 3 × 3

Step 2: Clearly, 729 is a perfect cube. Here we will be using laws of exponents.

729 = 36 [am × an = am+n]

729 = [32]3 [(am)n = amn]

729 = 93

Step 3: Now, we will apply cube root to both the sides of the above expression to take out the factor as a single term, which is in cubes.

3√729 = 3√(93)

So, here the cube root is cancelled by the cube of 9.

Hence, 3√729 = 9

Answer 2

first step: do prime factor method

2nd step: write prime factors as I do

3rd step: make pair of 3

4th step: remove braket by taking power 1/3

5th step: multiple it as I do

finally you will get answer..
