Q. 36427Which of the following is equivalent to the given expression?Choose 1 answer:(A) 43(B) 643(C) 818(D) 6424
Understand the expression: Understand the given expression 36427.This expression is asking for the cube root of 64 raised to the 27th power.
Simplify the base: Simplify the base 64 to a power of 2.Since 64 is 2 raised to the 6th power (26), we can rewrite 6427 as (26)27.
Apply power of a power rule: Apply the power of a power rule.The power of a power rule states that (am)n=a(m∗n). Therefore, (26)27 becomes 2(6∗27).
Calculate the exponent: Calculate the exponent.Multiply the exponents: 6×27=162. So, 2(6×27) is 2162.
Apply the cube root: Apply the cube root to the expression.The cube root of 2162 is the same as 23162 because 3am=a3m.
Calculate the new exponent: Calculate the new exponent.Divide the exponent by 3: 3162=54. So, 23162 is 254.
Determine the correct choice: Determine which answer choice matches 254.We need to find an answer choice that is equivalent to 254. Let's examine the choices:(A) 43 is 26, which is not equal to 254.(B) 643 is (26)3, which is 218, not 254.(C) 818 is 2540, which is 254, so this is the correct choice.(D) 2542 is 2543, which is 2544, not 254.
