Question

Tính

\(\left(-2\right)^2.3-\left(1^{10}+8\right):\left(-3\right)^2\)

Answer 1

Ta có: \(\left(-2\right)^2\cdot3-\left(1^{10}+8\right):\left(-3\right)^2\)

\(=4\cdot3-\dfrac{9}{9}\)

=12-1=11

Answer 2

\(\left(-2\right)^2.3-\left(1^{10}+8\right):\left(-3\right)^2\)

\(=4.3-9:9\)

\(=12-1=11\)

Answer 3

(-2)².3 - (1¹⁰ + 8) : ( -3)²

= 4.3 - ( 1 + 8) : 9

= 12 - 9 : 9

= 12 -1 

= 11
