+141 Hi Kitty this is how the problem is actually written: a 8⁄15 * a ‾ 1⁄3
+5478 Ok, so assuming this is dealing with exponents:
a^(8/15) * a^(-1/3)
= a(8/15) * a(-1/3)
= a (8/15) + (-1/3)
= a (1/5)
When you multiply a number x raised to an exponent by that same number x raised to a different exponent, the answer would be x raised to the sum of the exponential powers.

+8262 I can help. The answer is ((a*a8)/15)-((1/3)). That was the answer that I got on the calculator.
