Question

If someone could give me a step by step explanation that would be great!

Answer 1

3√6

Explanation:

if we factorize 54

54 = 2 x 3 x 3 x 3

hence

√54 = √ (2 x 3 x 3 x 3 )

= √ [ (2 x 3) x (3 x 3 ) ]

= √ (6 x 3² )

= √6 x √(3²)

= √6 x 3

= 3√6

Answer 2

answer is c

Explanation:

3 to the power of 2 and then 6 so then 9×6=54
