Нахождение значения степени:

• a) $$25^2 = 25 \times 25 = 625$$
• б) $$8^4 = 8 \times 8 \times 8 \times 8 = 4096$$
• в) $$7^3 = 7 \times 7 \times 7 = 343$$
• г) $$7^5 = 7 \times 7 \times 7 \times 7 \times 7 = 16807$$
• д) $$(-0,9)^3 = (-0,9) \times (-0,9) \times (-0,9) = -0,729$$
• е) $$(-2,4)^2 = (-2,4) \times (-2,4) = 5,76$$
• ж) $$(- \frac{1}{2})^5 = - \frac{1}{2^5} = -\frac{1}{32}$$
• з) $$(- \frac{1}{2})^6 = \frac{1}{2^6} = \frac{1}{64}$$
• и) $$-0,9^3 = -(0,9 \times 0,9 \times 0,9) = -0,729$$
• к) $$-2,4^2 = -(2,4 \times 2,4) = -5,76$$
