# having trouble with scientific calculator watch

1. i know how to do square root of a number, i just have to press √16 for example and it comes out as 4

but then i have to do sums like 64^5/6 or 64 to the power of 5/6 and i want to put (6√64)^5
but when i do 6√64 it comes out as 48 which i know is not what i wanted. how come when i put a number before √ on the calc, it becomes a different meaning as oppose to just √ being squared root? even when i put 2√16 it comes out as 8. i thought √ = 2√?

Try shift, then the square root

3. Wow, just. Wow.

shift square root is cubed root, but i want 6√

2√x means two times the root of x. You need to press the button that looks like a little x by the root symbol. It may be shift+root.

Then you'll probably have to do the fractional power way

Try shift+^
8. What calculator do you use?

There are a few possible ways of doing this, using the example of 64^(5/6)

First, inserting that directly into your calculator. I'm not sure which one you have, put surely you'll have a power button and a fraction button, which allows you to calculate that.

Or, you can use the root function on your calculator. What you're doing is multiplying the √64 by 6, rather than doing the 6th root of 64. For the 6th root, the button on your calculator should have a small number (possibly x) sitting on the square root sign. It'd be much easier to describe if you tell me which calculator you're using.
10. What model are you using? Can you find a pic of one online so we can see the buttons? Thanks.

that's exactly why, it all came back to me now that i need ⁶√64 instead of 6√64
but the problem is how do i get the ⁶. on my calc (canon f718sga) theres x√ by shift + ^ but then how do i get x to become ⁶? thanks

hopefully u can see the keys

Thanks. It does look like shift+^ will make it.

So to do the cube root of 5 you would type 3 then shift+^ then 5.

e.g. 6 x√ 64 will give you

The number you type before the x√ becomes the 'x'.

thank you!, it's annoying though how it appears as 6x√64 and not ⁶√64, it confuses my brain but it works so that's good, thanks!

thanks, i much prefer if the calculator shows a little 6 instead of 6x√ lol cos to me, it doesnt register well when it appear as that, but it works!!

That's why I picked a slightly fancier calculator
