Question

$2 \times ( {9}^{ - 2} + {3}^{3} )$
what's the answer​

Answer 1

Answer:

-145 Or -108

Step-by-step explanation:

Using Closure Prop.:

${2} \times {({9}^{-2} + {3}^{3})}$

= 2 X [-81] + 27

= [-162] + 27

= -145

Using Distributive Prop.:

$2 \ \times \ ({9}^{-2} \ + \ {3}^{3}) \\= \ 2 \ \times \ -81 \ + \ 2 \ \times \ 27\\= \ -162 \ + \ 54\\= \ -108$
