Guida verificata passo dopo passo
1
First, simplify the expression inside the parentheses. Calculate the value of \(9 - 8\).
Next, evaluate the exponentiation part of the expression. Calculate \$2^3$.
Multiply the results from the previous steps by their respective coefficients: multiply \(-4\) by the result of \(9 - 8\), and multiply \(-7\) by the result of \$2^3$.
After performing the multiplications, add the two products together to combine the terms.
Finally, simplify the sum to get the value of the entire expression.

Exponents

Exponents represent repeated multiplication of a base number. For example, 2³ means multiplying 2 by itself three times (2 × 2 × 2 = 8). Understanding exponents is essential for correctly simplifying expressions involving powers.
