Question

7. Simplify: (i) 5-{3-[2-(2 x (-3)+1)+(3-5)]} (ii) 7-[6-{5+(1-3+4}]​

Answer 1

Answer:

(i) 7

(ii) 8

Step-by-step explanation:

(i) 5 -{3-[2-(2×(-3)+1) + (3-5)]}

= 5 -{3-[2-(-6+1) + (-2)]}

= 5 -{3-[2-(-5)-2]}

= 5 -{3-[2+5-2]}

= 5 -{3-5}

= 5 -{-2}

= 5 + 2

= 7

(ii) 7-[6-{5+(1-3+4)}]

= 7-[6-{5+2}]

= 7-[6-7]

= 7-[-1]

= 7+1

= 8
