Solve the expression 2(1.6^0+7)−4.9^0.(1 point)
2(1.6^0+7)−4.9^0
To solve the expression, we follow the order of operations: parentheses first, then exponents, and finally addition/subtraction.
First, let's simplify the exponents:
1.6^0 = 1 (any number raised to the power of 0 is always 1)
4.9^0 = 1 (same reason as above)
Now, let's simplify the expression:
2(1 + 7) - 1(-4.9) = 2(8) - (-4.9) = 16 + 4.9 = 20.9
Therefore, the solution to the expression 2(1.6^0 + 7) - 4.9^0 is 20.9.
To solve the expression 2(1.6^0+7)−4.9^0, we can follow the order of operations (also known as PEMDAS or BODMAS).
Step 1: Simplify the exponents.
Since any number raised to the power of 0 is equal to 1, 1.6^0 and 4.9^0 both equal 1.
So the expression becomes: 2(1 + 7) - 1 * 1.
Step 2: Perform addition.
Inside the parentheses, 1 + 7 equals 8.
So the expression becomes: 2(8) - 1 * 1.
Step 3: Perform multiplication.
2 multiplied by 8 equals 16.
1 multiplied by 1 equals 1.
So the expression becomes: 16 - 1.
Step 4: Perform subtraction.
16 minus 1 equals 15.
Therefore, the solution is 15.
