Question

Efectuați: 5×[5+5×(5^3-5^3)]+3×5^2=
b. (6+2^10:2^8):10^5-9×10=

Ma poate ajuta cineva cu aceste calcule!!! Va rog!!!​

Answer 1

5×[5+5×(5³-5³)]+3×5²=

5×(5+5×0)+3×25=

5×5+75=25+75=100

(6+2¹⁰:2⁸):10⁵-9×10=

(6+2²):10⁵-90

10:10⁵-90

Answer 2

Răspuns:

a. 5x(5+5x0)+75=25+75=100

b. (6+2^2):10^5-90=10:10^5-90=10^-4-90=10/100000-90=1/10000-900000/10000=-899999/10000=-89,99
