Question

a.) 1,2²:1,2-1,2
b.) 6,7+6,7²:6,7-6,7
c.) 123,23-3,4²:3,4-12,57
​

Answer 1

Explicație pas cu pas:

$({1.2}^{2} \div 1.2) - 1.2 = 1.2 - 1.2 = 0$

$6.7 + ({6.7}^{2} \div 6.7) - 6.7 = 6.7 + 6.7 - 6.7 = 6.7$

$123.23 -( {3.4}^{2} \div 3.4) - 12.57 = 123.23 - 3.4 - 12.57 = 119.83 - 12.57 = 107.26$

Answer 2

a) 1,2 - 1,2 = 0
b) 6,7 + 6,7 - 6,7 = 6,7
c) 123,23 - 3,4 - 12,57 = 107,26
