Explicație pas cu pas:
a)
(9×2-7)×(3²⁰:3¹⁷-2⁸×2⁶:2¹²+1)
(18-7)×(3³-2²+1)
11(27-4+1)
11×24
264
b)
[tex]3(( \frac{5}{2} ) {}^{2} + 0.2(16.8 - 3.4))[/tex]
[tex]3( \frac{25}{4} + 0.2 \times 13.4)[/tex]
[tex]3( \frac{25}{4} + 2.68)[/tex]
[tex]3( \frac{25}{4} + \frac{67}{25} )[/tex]
[tex]3 \times \frac{893}{100} [/tex]
[tex] \frac{2679}{100} [/tex]
