Question

rápido PRF calcule : a) √13²-12² b) √1,21 + √1,44 + √49 + √0,16 + √0,36 c) √16 + √1/9 + √1/4 + 7¹ ​

Answer 1

a) √(13²-12²) = √(169 - 144) = √25 = 5

b) √1,21 + √1,44 + √49 + √0,16 + √0,36

= 1.1 + 1.2 + 7 + 0.4 + 0.6 = 10.3

c) √16 + √1/9 + √1/4 + 7¹ ​

= 4 + 1/3 + 1/2 + 7

mmc = 6

= 24/6 + 2/6 + 3/6 + 42/6 = 71/6
