express 4underroot2 to the power of 2?

Answer 1

It can be expressed as {4*sqrt(2)}^2
or {sqrt 4}^2
1. 4 underroot 2
=4*sqrt(2)
now,4underroot2 to the power of 2
={4*sqrt(2)}^2
=4^2*2^0.5*2
=16*2^1.0
=16*2
=32.
2. {sqrt 4}^2
=2^2
=4

Answer 2

This question isn't very clear. First,
I will assume you mean √2/4.
In that case you have 2^(1/2) * 2^(-2) = 2^(-3/2)
If you square this you have 2^-3 or 1/8.
If you mean 4*√2, its square is 16*2 = 32.

Answer 3

Do you perhaps mean four, under [root 2] (meaning: square root), and then take the result to the power of two?

If so: "underroot2" and "to the power of 2" cancel each other out, so I'd just write "4".

Answer 4

? What is a underroot

If what you are asking if square root of 4,
raised to the power 2.

The answer is 4.

Look in a dictionary for underroot ,
I do not know that word exists
If that the question 4 root of 2
the raised too 2 power ==square root 2

Answer 5

square of 4 is 16 but square root of 16 not only 16 but it is +,-4

Answer 6

[4*sqrt2]^2
=16*2
=32

Answer 7

[4(2^.5)]^2
=32

Answer 8

the answer to that is 4.. coz the square root will be cancelled if u square it. =)
