: fill in the missing description
: 48 was this cube root of 64=4 so the answer was just 64 4/3=2
Let me guess!
"48" is the problem number, right?
And "this cube root of 64=4" means "the cube root
of 64 is 4".
"So the answer was just 64 4/3=2"?
Sorry, but the answer to WHAT?
What was the question?
Where did the denominator of 3 comes from?
And how did the answer become 2?
I won't ask: "Fill in the missing description" ??
: now i dont understand this onecube root of -216=-6 i have to find the rational exponent form
It asks "What number was cubed to get -216?"
Try -6.
"Rational exponent" means fractional exponent.
sqrt(X) = X^(1/2). cbrt(X) = X^(1/3). Okay?
