11. [tex] \sqrt{784} [/tex] = 28
[tex] \sqrt{64} [/tex] = 8
[tex] \sqrt{169} [/tex] = 13
[tex] \sqrt{16} [/tex] = 4
[tex] \frac{28+8*13}{4} [/tex]
= [tex] \frac{28+104}{4} [/tex]
= [tex] \frac{132}{4} [/tex]
= 33 (B)
12. 60² = 3600
[tex] \sqrt{144} [/tex] = 12
2³ = 8
3600 ÷ 12 + 8
= 300 + 8
= 308 (A)
13. [tex] \frac{48}{72} [/tex] = [tex] \frac{24}{36} [/tex] = [tex] \frac{12}{18} [/tex] = [tex] \frac{6}{9} [/tex]
= [tex] \frac{2}{3} [/tex] (A)
