Answer:
506 is your answer.
Step-by-step explanation:
Okay so you gotta focus on this rule: BODMAS or PEMDAS.
BODMAS: bracket order division multiplication addition subtraction (order means the degree for eg degree of 2⁴ is 4 and degree of 8¹ is 1.)
PEMDAS: parenthesis exponent multiplication division addition subtraction
We've to solve any numerical in the order of the given rule; so 1st you'll do bracket then exponent etc.
So you may say that in the 1st rule, I took division earlier and in the 2nd I took multiplication earlier. It's because whichever operator comes before, we use it.
eg. 8 ÷ 2 × 3 = 4 × 3 = 12 (1st we carry out division and then multiplication)
8 × 2 ÷ 3 = 16 ÷ 3= 5.3333333... (here we did multiplication earlier because it's given earlier)
I hope the concepts are clear, let's jump into the problem
___________________
8³ - 9 × 2 ÷ 3 = ___
512 - 9 × 2 ÷ 3 = ___
512 - 18 ÷ 3 = ___
512 - 6 = ___
506
___________
As you saw, I first dealt with the exponent, then with the multiplication and then with the division and then with the subtraction; we solved using the laws.
Answer:
512-18/3
512-6
