Questions & Step-by-Step Solutions

If b = 2^(1/3), what is b^6?
Correct Answer: 4
  • Step 1: Start with the value of b, which is given as b = 2^(1/3).
  • Step 2: We need to find b^6, so we write it as (2^(1/3))^6.
  • Step 3: Use the power of a power rule, which says (a^m)^n = a^(m*n). Here, a = 2, m = 1/3, and n = 6.
  • Step 4: Multiply the exponents: (1/3) * 6 = 6/3 = 2.
  • Step 5: Now we have (2^(1/3))^6 = 2^(2).
  • Step 6: Calculate 2^2, which equals 4.
