Answer 1

a) 7² = 7 * 7 = 49

b) -4³ = 4*4*4 = -64

d) 10⁶ = 10 * 10 * 10 * 10 * 10 * 10 = 1 000 000

e) $(\frac{5}{6})^2 = \frac{5}{6} * \frac{5}{6} = \frac{5*5}{6*6} = \frac{25}{36}$

f) (1,2)² = 1,2 * 1,2 = 1,44

g) $(\frac{3}{4})^4 = \frac{3}{4} *\frac{3}{4} *\frac{3}{4} * \frac{3}{4} = \frac{3*3*3*3}{4*4*4*4} = \frac{81}{256}$

h) $(\frac{1}{10})^5 = \frac{1}{10}*\frac{1}{10}*\frac{1}{10}*\frac{1}{10}*\frac{1}{10} = \frac{1*1*1*1*1}{10*10*10*10*10} = \frac{1}{100000}$

i) (-4)³ = (-4) * (-4) * (-4) = -64
