Simplify: a^3 × a^3 × 5a^4 . Maths Questions - Toppr Ask

Webb28 juni 2024 · The answer is 3^5 (which is also = 243). Step-by-step explanation: We can use the exponent or product rule for powers (2 and 3) that have the same base (3): in order to multiply similar bases that have their respective powers, add the exponents, which in this case are 2 and 3, viz: 3^2 x 3^3 = 3^(2+3) = 3^5. 3^5 = 3 × 3 × 3 × 3 × 3 = 243.
