Q. Select all the expressions that are equivalent to 73076\frac{7^{30}}{7^6}.\newlineMulti-select Choices:\newline(A) 7247^{24}\newline(B) 175\frac{1}{7^5}\newline(C) 7367^{36}\newline(D) 1724\frac{1}{7^{-24}}
  1. Simplify Expression: Simplify the expression 730/767^{30}/7^{6} using the properties of exponents.\newlineWhen dividing powers with the same base, we subtract the exponents.\newline730/76=7(306)=7247^{30}/7^{6} = 7^{(30 - 6)} = 7^{24}
  2. Check Choice (A): Check each answer choice to see if it is equivalent to 7247^{24}.
    (A) 7247^{24} is clearly equivalent because it matches the result from Step 11.
  3. Check Choice (B): Check choice (B) 175\frac{1}{7^5}. 175\frac{1}{7^5} is not equivalent to 7247^{24} because the exponent is not the same and the expression is a reciprocal, not a product.
  4. Check Choice (C): Check choice (C) 7367^{36}. 7367^{36} is not equivalent to 7247^{24} because the exponent 3636 is not the result of subtracting 66 from 3030.
  5. Check Choice (D): Check choice (D) 1/7241/7^{-24}. 1/7241/7^{-24} is equivalent to 7247^{24} because the negative exponent indicates a reciprocal, and taking the reciprocal of a reciprocal gives the original value.
