Answer:

7/ 36

Step-by-step explanation:

Roll of 2 fair six sided die :

Sample space = 6² = 36

Sum of 7:

(1,6) ; (6,1) ; (3,4) ; (4,3) ; (2,5) ; (5,2) = 6

Probability = required outcome / Total possible outcomes

Required outcome = 7

Total possible outcomes = 36

P(obtaining a sum of 7) = 7 / 36

vichka [17]

Answer:

By property of power of a power:

$(3^{\frac{1}{4}} )^{2}$ = $3^{(\frac{1}{2})}$

Step-by-step explanation:

Given that $(3^{\frac{1}{4}} )^{2}$

The property of power of a power is given by,

= $(a^{b} )^{2}$

= $(a^{b} )\times (a^{b} )$

= $(a^{(b+b)} )$

Using the property of power of a power:

= $(3^{\frac{1}{4}} )^{2}$

= $(3^{\frac{1}{4}} )\times (3^{\frac{1}{4}} )$

= $3^{(\frac{1}{4}+\frac{1}{4})}$

= $3^{(\frac{1}{2})}$
