(a²b)³ = a²⁽³⁾b¹⁽³⁾ = a⁶b³

The exponent tells you how many places to move the decimal. The positive/negative sign tells you which direction to move the decimal (negative is left, positive is right).
8.4 x 10⁻⁵ <em>move the decimal 5 places to the left</em> = 0.000084
So 1 and 1/3 times 5/6
first convert 1 1/3 into improper fraction (x/y)
1 1/3=3/3+1/3=4/3
4/3 times 5/6=(4 times 5)/(3 times 6)=20/18=10/9
the answer is 10/9 or 1 and 1/9 or 1 1/9
