Question

Вычислите значение выражения
$( frac{4}{7} )^{2} * 1 frac{3}{4} - (-3) ^{3} = 2^{3} *0,5 ^{3}+ (-2,47) ^{0}= 19 ^{7} * (19 ^{2} ) ^{3} : 19^{11} = frac{4 ^{6} }{8 ^{3} } =$

Answer 1

16/49*7/4 + 27 = 64/196 + 27 = 16/49 + 27 = 27 16/49 = 1339/49

8*1/8-1=1-1=0

19⁷*19⁶/19¹¹=19¹³/19¹¹=19²=381

4⁶/8³=2¹²/2⁹=2³=8

Answer 2

(4/7)² * 1 3/4 - (-3)³ = 16/49 * 7/4 - (-27) = 4/7 + 189/7 = 193/7 = 27  4/7
2³ * 0,5³ + (-2,47)⁰ = 8 * 0,125 + 1 = 1+1= 2
19⁷ * (19²)³ : 19¹¹ = 19⁷ * 19⁶ : 19¹¹ = 19¹³ : 19¹¹ = 19² = 361
4⁶ / 8³ = 2¹² / 2⁹ = 2³ = 8
