Q. Which expression is equivalent to 46×96?Choices:(A) 3612(B) 3636(C) 366(D) 1/366
Identify Bases and Exponents: Identify the base and the exponents in the given expression.The given expression is 46×96. Here, 4 and 9 are the bases, and both are raised to the exponent 6.
Recognize Perfect Squares: Recognize that 4 and 9 are perfect squares. 4 is the square of 2 (since 22=4), and 9 is the square of 3 (since 32=9). This can be rewritten as (22)6×(32)6.
Apply Power of Power Rule: Apply the power of a power rule.According to the power of a power rule, (ab)c=a(b∗c). Therefore, (22)6 becomes 2(2∗6) and (32)6 becomes 3(2∗6).
Calculate New Exponents: Calculate the new exponents. 2(2∗6)=212 and 3(2∗6)=312. So the expression now is 212∗312.
Combine Bases with Multiplication: Combine the bases using multiplication.Since both bases are raised to the same exponent, we can multiply the bases together and keep the common exponent. This gives us (2×3)12.
Calculate Base Multiplication: Calculate the base multiplication. 2×3 equals 6. So the expression now is 612.
Recognize Product of 4 and 9: Recognize that 6 is the product of 4 and 9.Since 4×9 equals 36, and we have 612, we can rewrite this as 366.
Choose Equivalent Expression: Choose the equivalent expression for 46×96. The equivalent expression is 366, which corresponds to choice (C).
