Simplifying Expressions with Exponents
Simplify algebraic expressions with exponents in Grade 9 Algebra using product, quotient, and power rules. Reduce each expression to a single term with no negative exponents.
Key Concepts
Property Exponents are simplified after grouping symbols but before multiplication, division, addition, and subtraction, following the PEMDAS order.
Examples $5 \cdot 2^3 10 = 5 \cdot 8 10 = 40 10 = 30$ $50 (1+2)^2 \cdot 3 = 50 3^2 \cdot 3 = 50 9 \cdot 3 = 50 27 = 23$ $4^3 + 9 \div 3 = 64 + 9 \div 3 = 64 + 3 = 67$.
Explanation Exponents get priority after parentheses. This is the 'E' in PEMDAS. Always calculate the value of any powers before you move on to multiplying or dividing. This step simplifies the expression significantly, making the remaining calculations more straightforward and helping to prevent common calculation mistakes down the line.
