(a) 30 X 4-20 + 75 : 25
(b) 72 = [36 = (3 x 4)]
(c) 200 x [22 - (16 = 4)
4. Evaluate.
le (a) (25 - 15) [8 + 12 + 17 -1 + 3}]
(b) 40 x [8 - 24 = (98-94)
5. Find the value of
3 - [3 - [3 - (3 + 3-3)}]


plz solve it, I will mark you as the brainliest. ​

Answer 1

Step-by-step explanation:

we solve by applying bodmas rule

question 3rd

• (a) 30×4-20+75:25
• 30×4-20+3=120-20+3=120-17=107
• (b)72=[36=(3×4)]
• 72=[36=12]
• 72=36=12(this is not equal)

question 4th

• (a) (25-15)[8+12+17-1+3]
• 10[40-1]
• 10×39=390
• (b) 40×[8-24=(98-94)]
• 40×[8-24=4]here = is not sing is used plss correct it

question 5th

• 3-[3-{3-(3+3-3)}]
• 3-[3-{3-3}]
• 3-[3-0]
• 3-3
• 0
