Q. y3z⋅y13z8Which of the following is equivalent to the given expression for all real values of y and z ?Choose 1 answer:(A) y4z3(B) y8z4(C) y8z4z(D) y15z4y
Property of square roots: We are given the expression y3z⋅y13z8. To simplify this expression, we will use the property of square roots that a⋅b=a⋅b.
Multiplying the square roots: Now we multiply the two square roots together: y3z×y13z8=(y3z)×(y13z8).
Combining terms under the square root: Next, we combine the terms under the square root: (y3z)⋅(y13z8)=y3+13⋅z1+8.
Adding exponents of like bases: We add the exponents of like bases: y(3+13)⋅z(1+8)=y16⋅z9.
Simplifying the square root of each term: Now we simplify the square root of each term: y16⋅z9=y16⋅z9.
Dividing exponents by 2: Since y16 and z9 are perfect squares, we can take the square root of each: y16⋅z9=y216⋅z29.
Recognizing z4.5 as z4z: We simplify the exponents by dividing them by 2: y216⋅z29=y8⋅z4.5.
Matching with option (C): We recognize that z4.5 is the same as z4z: y8⋅z4.5=y8⋅z4⋅z.
Matching with option (C): We recognize that z4.5 is the same as z4z: y8⋅z4.5=y8⋅z4⋅z. We compare our result with the given answer choices and find that it matches with option (C) y8z4z.
