Q. Select all the expressions that are equivalent to 55×535^5 \times 5^{-3}.\newlineMulti-select Choices:\newline(A) 1515\frac{1}{5^{-15}}\newline(B) 5155^{-15}\newline(C) 152\frac{1}{5^{-2}}\newline(D) 152\frac{1}{5^2}
  1. Use Exponent Properties: To solve this problem, we need to use the properties of exponents. Specifically, when multiplying two powers with the same base, we add the exponents.\newline55×53=55+(3)=525^5 \times 5^{-3} = 5^{5 + (-3)} = 5^2.
  2. Compare with Choices: Now we need to compare the result 525^2 with each of the given choices to determine which are equivalent.\newline(A) 1515\frac{1}{5^{-15}} is not equivalent because the negative exponent indicates the reciprocal, and the base and exponent do not match 525^2.
  3. Analysis of Choices: (B)515(B) 5^{-15} is not equivalent because the exponent 15-15 does not match the exponent 22 in 525^2.
  4. Analysis of Choices: (B) 5155^{-15} is not equivalent because the exponent 15-15 does not match the exponent 22 in 525^2. (C) 152\frac{1}{5^{-2}} is equivalent because the negative exponent indicates the reciprocal, and when we take the reciprocal of 525^{-2}, we get 525^2.
  5. Analysis of Choices: (B) 5155^{-15} is not equivalent because the exponent 15-15 does not match the exponent 22 in 525^2. (C) 152\frac{1}{5^{-2}} is equivalent because the negative exponent indicates the reciprocal, and when we take the reciprocal of 525^{-2}, we get 525^2. (D) 152\frac{1}{5^2} is equivalent because it is the reciprocal of 525^2, which is the same as 525^2.
