Solution steps

7777

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

777 = 7^{\frac{1}{2}} \cdot 7^{\frac{1}{2}} \cdot 7^{\frac{1}{2}} = 7^{\frac{1}{2} + \frac{1}{2} + \frac{1}{2}}

= 7 \cdot 7^{\frac{1}{2} + \frac{1}{2} + \frac{1}{2}}

Combine the fractions

\frac{1}{2} + \frac{1}{2} + \frac{1}{2} : \frac{3}{2}

= 7 \cdot 7^{\frac{3}{2}}

7^{\frac{3}{2}} = 77

= 7 \cdot 77

Multiply the numbers:

7 \cdot 7 = 49

= 497
