66×k2
Evaluate
216k4
Rewrite the exponent as a sum
62+1k4
Use am+n=am×an to expand the expression
62×6k4
Reorder the terms
62k4×6

Show Solution

Find the roots
k=0
Evaluate
216k4
To find the roots of the expression,set the expression equal to 0
216k4=0
Since the left-hand side is always positive or 0,and the right-hand side is always 0,the statement is true for any value of k
216k4=0,k∈R
Calculate
216k4=0
Simplify the root
