rationalize the denominator of the expression assume that all variables are positive

^3�ã7/^3�ã10

i cant get that sign on my pc its 2nd x2 on a graphing calc

To rationalize the denominator of the expression ^3�ã7/^3�ã10, you need to eliminate any square root or radical from the denominator. Here's how you can do it:

Step 1: Simplify the expression if possible.
- Since both the numerator and denominator have the same cube root (denoted by ^3), you can cancel them out:
^3�ã7/^3�ã10 = ^3�ã(7/10)

Step 2: Rationalize the denominator by multiplying the expression by the conjugate of the denominator.
- The conjugate of ^3�ã10 is ^3�ã10. Multiply both the numerator and the denominator by this conjugate:
[(^3�ã7) * (^3�ã10)] / [(^3�ã10) * (^3�ã10)]

Step 3: Simplify the expression further.
- The numerator can be expanded as:
(^3 * ^3) * (^ã7 * ^ã10) = ^9�ã70

- The denominator can be expanded as:
(^3 * ^3) * (^ã10 * ^ã10) = ^9�ã100

Step 4: Simplify the remaining radical expression.
- ^9�ã100 can be simplified as ^3�ã10 since the cube root of ^9 is ^3.

Therefore, rationalizing the denominator of the expression ^3�ã7/^3�ã10 gives you the simplified form ^3�ã10/^3�ã10, which can be further simplified to just 1.
