Q. Select the equivalent expression 6×6×6×6×6(A) (62)3(B) 25⋅35(C) 6166(D) 32⋅23
Evaluate Options: We need to find an expression that is equivalent to multiplying 6 by itself 5 times, which is written as 65. Let's evaluate each option to see which one is equivalent to 65.
Option (A): Option (A) is (62)3. Using the power of a power rule, which states that (am)n=am∗n, we calculate (62)3 as 62∗3=66. This is not equal to 65.
Option (B): Option (B) is 25×35. Using the rule that (ab)n=an×bn, we can rewrite 65 as (2×3)5, which is equal to 25×35. This option is equivalent to 65.
Option (C): Option (C) is 66/61. Using the quotient of powers rule, which states that am/an=a(m−n), we calculate 66/61 as 6(6−1)=65. This option is also equivalent to 65.
Option (D): Option (D) is 32×23. This option is not equivalent to 65 because 32×23=9×8=72, which is not the same as 6 multiplied by itself 5 times.
