Zero Power Rule of Exponents Practice
Math 8 Q1 (Pre-Algebra) / Exponent Rules
Solve the expression 2(1.6^0+7)−4.9^0. (1 point)
To solve this expression, we need to apply the Zero Power Rule of exponents. According to the Zero Power Rule, any non-zero base raised to the power of zero is equal to 1.
So, 1.6^0 is equal to 1, and 4.9^0 is also equal to 1.
Now plug in these values into the expression:
2(1 + 7) - 1
We simplify the expression inside the parentheses first, which gives us:
2(8) - 1
Now, we can multiply 2 and 8:
16 - 1
Finally, we subtract 1 from 16:
15
Therefore, the answer is 15.
To solve the expression 2(1.6^0 + 7) - 4.9^0, we will start by simplifying the exponents using the zero power rule.
Step 1: According to the zero power rule, any number (except zero) raised to the power of 0 is equal to 1.
So, 1.6^0 = 1, and 4.9^0 = 1.
Step 2: Now, we can simplify the expression.
2(1 + 7) - 1
Step 3: Inside the parentheses, we perform the addition operation first:
2(8) - 1
Step 4: Finally, we perform the multiplication and subtraction operations:
16 - 1
Step 5: Subtracting 1 from 16, we get the final answer:
15
Therefore, the expression 2(1.6^0 + 7) - 4.9^0 simplifies to 15.
