Question

What is 2^3/2 equal to?

Answer 1

Too many math questions get posted around here without parentheses, that desperately need to have them. A couple of other answerers here have already pointed out the ambiguity in what you wrote. You can make it clear using the additional details feature.

OK, that said, it looks like you meant 2^(5/2) - 2^(3/2), because (2^5)/2 - (2^3)/2 would be so much easier. But please, in the future, practice safe math -- use parentheses!

Using the rule: a^(b+c) = (a^b)(a^c),

2^(5/2) - 2^(3/2)
= 2^(1 + 3/2) - 2^(3/2)
= 2^(3/2) (2 - 1)
= 2^(3/2)
= 2^(1 + 1/2)
= 2 * 2^(1/2)
= 2√2

Answer 2

4

Answer 3

google it

Answer 4

2^3
---
2


or

2^3 / 2 ?

Answer 5

\(\bf \cfrac{2^3}{2}?\)

Answer 6

it is 4

Answer 7

That's not one of the answer choices

Answer 8

Let me post the answer choices, give me a second

Answer 9

You didn't say if it is \(\normalsize\color{blue}{ 2^{3/2}}\) or \(\normalsize\color{blue}{ 2^{3}/2}\)

Answer 10

\(\Large a^{\frac{{\color{blue} n}}{{\color{red} m}}} = \sqrt[{\color{red} m}]{a^{\color{blue} n}} \qquad \qquad

\sqrt[{\color{red} m}]{a^{\color{blue} n}}=a^{\frac{{\color{blue} n}}{{\color{red} m}}}\)

Answer 11

It is 2^(3/2)

Answer 12

then use the formula jdoe0001 posted

Answer 13

It's not one of the answers

Answer 14

2^(3/2) = ²√ 2³ = √8

Answer 15

Still not one of the choices ?

Answer 16

It would be 2 to the square root of 8?

Answer 17

\[2\sqrt{8} ?\]

Answer 18

It is \(\normalsize\color{black}{ \sqrt[2]{8}}\), which is the exact same thing as \(\normalsize\color{black}{ \sqrt{8}}\)

Answer 19

Okay, thanks for showing me how to do it in the process :D

Answer 20

You never fail to disappoint

Answer 21

Wait

Answer 22

Did I say that wrong

Answer 23

You never fail to solve the question!

Answer 24

you said, \(\normalsize\color{black}{ 2\sqrt{8}}\) and it is not that, it is \(\normalsize\color{black}{ \sqrt[2]{8}}\)

Answer 25

it is not \(\normalsize\color{black}{ 2\times\sqrt{8}}\), just \(\normalsize\color{black}{ \sqrt{8}}\)

Answer 26

its d

Answer 27

no

Answer 28

I gave you the answer, didn't I ?
