Look at the explanation to understand.

Step-by-step explanation:

Step 1.

Apply the rule. (a) = a

For this expression, (2) = 2


√(4)*2

Step 2.

Multiply 4 by 2.

4 × 2 = 8

Step 3.

Prime factorization of 8: 2³


√(2^3)

Step 4.

Apply the exponent rule.
(a^b^+^c=a^b* a^c)

2³ = 2² × 2


√(2^2*2)

Step 5.

Apply the radical rule.
√(ab)=√(a)√(b), a\geq 0, b\geq 0


√(2^2)√(2)

Step 6.

Apply the radical rule again.
√(a^2)=a, a\geq 0


2√(2)=4

Hence, 4 is the answer.
