Zero Power Rule of Exponents Practice

Question

Math 8 Q1 (Pre-Algebra) / Exponent Rules

Solve the expression 2(1.6^0+7)−4.9^0. (1 point)

Answer 1

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.
