Answer:
[tex]3 \frac{1}{16} [/tex]
Step-by-step explanation:
first lets change the question into proper fraction
[tex]1 \frac{3}{4} = \frac{7}{4} [/tex]
now lets find the square of the number
[tex] { \frac{7}{4} }^{2} = \frac{49}{16} [/tex]
The question says the answer must be a mixed number so lets change it
[tex] \frac{49}{16} = 3 \frac{1}{16} [/tex]
