simplify 36-2x6+7X4
To simplify the expression 36-2x6+7x4, first perform the multiplication:
36 - 12 + 28
Then perform the addition and subtraction:
36 - 12 + 28 = 24 + 28
Finally, combine like terms:
24 + 28 = 52
Therefore, the simplified expression is 52.
simplify 27-3^3+4x2^2-6
To simplify the expression 27-3^3+4x2^2-6, follow the order of operations (PEMDAS):
First, evaluate the exponentiations:
27 - 27 + 4 x 4 - 6
Simplify the multiplications:
27 - 27 + 16 - 6
Next, perform the additions and subtractions:
(27 - 27) + 16 - 6 = 0 + 16 - 6 = 16 - 6 = 10
Therefore, the simplified expression is 10.
evaluate a+b^4 where a=2, b+3
To evaluate the expression a+b^4 with a = 2 and b = 3, substitute the given values into the expression:
a + b^4 = 2 + (3)^4
Evaluate the exponentiation first:
2 + 81
Then perform the addition:
2 + 81 = 83
Therefore, the evaluation of the expression a+b^4 with a = 2 and b = 3 is 83.
simplify 6/3x2-5+7x2
To simplify the expression 6/3x2-5+7x2, we follow the order of operations (PEMDAS):
First, perform the multiplications and divisions from left to right:
6/3x2 = 2x2 = 4
Next, perform the additions and subtractions from left to right:
4 - 5 + 7x2 = -1 + 14
Finally, perform the addition:
-1 + 14 = 13
Therefore, the simplified expression is 13.
