8 in. 4) The opposite of squaring a number is finding the square root. 8^2=64 so sqrt (64)=8 4) What is another square root of 64? -8 -4 2 16 A=64in.^2

#Explanation1) The question asks for another square root of 64. By definition, a square root of a number is a value that, when multiplied by itself, gives the original number. For any positive real number, there are always two square roots: one positive and one negative. This is because both a positive number and its negative, when squared, result in a positive number. For example, both 8 and -8 are square roots of 64 because and .2) The options given are -8, -4, 2, 16, and 8 in. The only other square root of 64 among these options is -8. The other options, when squared, do not result in 64. For instance, , , and . 3) The option "8 in." is not a valid answer because it includes a unit of measurement (inches), which is not relevant to the concept of square roots. Square roots are mathematical operations and do not involve units of measurement.#Answer-8
