Dauuu coroanaaa

Answer 1

Răspuns:

a)(2+3^2)*5=(2+9)·5=11·5=55

b)(6+3^2)*(5^2-15)=(6+9)·(25-15)=15·10=150

c)(13^2-19):(4^2-6)=(169-19):(16-6)=150:10=15

d)7^3*(3^2-2^3-1)=343·(9-8-1)=343·0=0

Answer 2

Răspuns:

Explicație pas cu pas:

a)  ( 2 + 3² ) x 5 = ( 2 + 9 ) x 5 = 11 x 5 = 55

b)  ( 6 + 3² ) x ( 5² - 15 ) = ( 6 + 9 ) x ( 25 - 15 ) = 15 x 10 = 150

c)  ( 13² - 19 ) : ( 4² - 6) = ( 169 - 19 ) : ( 16 - 6 ) = 150 : 10 = 15

d)  7³ x ( 3² - 2³ - 1) = 7³ x ( 9 - 8 - 1 ) = 7³ x 0 = 0
