I'm trying to program exponents into my Scratch project, but it's not working properly. I tried using the “join” block to evaluate 2^3, which should be 8, but I ended up getting a completely different number. Does anyone know how to program exponents?

See here

I know how!!!

I made a block for it


define Exponent (a)^(b)
set to (a)
repeat (b-1)
set to ((a)*(returning value))
end

then use returning value as your response input

I came here to search for the answer to a decimal exponent, something like 135^0.6309. Can anyone help me?

From the Scratch Wiki (more detail there including exceptions): https://en.scratch-wiki.info/wiki/Solving_Exponents

set [base v] to [135]
set [exponent v] to [0.6309]
set [Result v] to ([10 ^ v] of ((exponent) * ([log v] of ([abs v] of (base)))))

did you mean

define Exponent (a)^(b)
set [returning value v] to (a)
repeat ((b) - (1))
 set [returning value v] to ((a)*(returning value))
end

shouldnt there be a dedicated block for this (and squere-, triple-, quadruple- roots) in scratch???
THis really should be added!

Square root is in the drop down list. The others are not generally standard in any language I've used and easy to work around with logs.

(Fourth root is sqrt of sqrt.)

Yes. there is a way.
