Answer 2

Question 1) :- simplify :- (310 ÷ 37) * 3 - 5

Solution :-

→ (310 ÷ 37) * 3 - 5

according to BODMAS rule solving bracket first,

→ (310/37) * 3 - 5

solving multiply now,

→ (310 * 3)/37 - 5

→ (930/37) - 5

subtracting by taking LCM now,

→ (930 - 37 * 5)/37

→ (930 - 185)/37

→ (745/37) (Ans.)

Question 2) :- simplify :- (3^10 ÷ 3^7) * 3^( - 5)

Solution :-

→ (3^10 ÷ 3^7) * 3^( - 5)

using a^m ÷ a^n = a^(m - n) in bracket,

→ 3^(10 - 7) * 3^(-5)

→ 3³ * 3^(-5)

using a^m * a^n = a^(m + n) now,

→ 3^(3 - 5)

→ 3^(-2)

using a^(-m) = 1/a^m now,

→ 1/3²

→ (1/9) (Ans.)
