# Cube Roots Self Checking Table

Hello,
I am trying to have a self checking table answer that is a cube root. I have put the nthroot but I can’t seem to find an example of where to put the 3 to have it be cube root. The answer should be 2 cube root 7.

isCorrect6= table4.cellNumericValue(1,1)=numericValue(2\3nthroot{7})
correct = this.cellNumericValue(1,1) = 3.826

cellContent(1, 2):

when table4.submitted and isCorrect6 “ Yes!”
when not(table4.submitted) “”
otherwise “Try Again

correct: this.cellNumericValue(1,1)=numericValue(2\3nthroot{7})

Here’s how it comes up if you copy-paste from the calculator: 2\sqrt[3]{7}, but you’ll want to round or use a range.

isCorrect6 = this.cellNumericValue(1,1)>3.825
and this.cellNumericValue(1,1)<3.827


or

isCorrect6=numericValue("\round(\${this.cellNumericValue(1,1)},3)")=
numericValue("\round(2\sqrt[3]{7},3)")
