To avoid confusion, remember PEMDAS. This is the order of operation.
Parenthesis, Exponents, Multiply, Divide, Add, Subtract
21 ÷ 7 + 20 * 102 * 2 - 3
No parenthesis and no exponents, proceed to multiplication.
20 * 102 * 2 = 4,080
Then, perform division
21÷7 = 3
Then, do addition
3 + 4080 = 4083
Lastly, do subtraction
4,083 - 3 = 4,080
So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080
Perimeter (P) of a square = 4s ; where s is the length of a side
1 yd = 4s
yd = s
Area (A) of a square = s²
= (
)²
Now, convert from yard to foot to inch:
()² x (
)² x (
)²
= (3 x 3 x 12 x 12) ÷ (4 x 4)
= 81 in²
Answer:
4-13 is -9 and -9 to the 4th power is 6561 -6 is 6555
Then you do 25/5 which is 5 so 6555 over 5 is 1311
1311 minus the absolute value of -2 which is 2 so 1311 minus 2 is 1309
Step-by-step explanation:
1309
