Question

If x³= 27 and y³= 64, then find the value of xy​

Answer 1

${x}^{3} = 27 \\ {x}^{3} = 3 \times 3 \times 3 \\ x = 3 \\ \\ \\ {y}^{3} = 64 \\ {y}^{3} = 4 \times 4 \times 4 \\ y = 4$

Answer 2

Answer:

$xy = 12$

Step-by-step explanation:

${x}^{3} = 27 \\ x \times x \times x = 3 \times 3 \times 3 \\ so \\ x = 3$

${y}^{3} = 64 \\ y \times y \times y = 4 \times 4 \times 4 \\so \\ y = 4$

$now \\ x \times y = 3 \times 4 \\ = 12$
