Answer:
Not B, A or C I believe it is C
Explanation:
x^4y and 4x^2
(x^4×y)×(4x²) = (yx^4)(4x²) = = 4× y × x^4 × x² = 4yx^6
exponents of the same base add
lets try this with REAL numbers to check the answer let x = 2 and y =3
(yx^4)(4x²) = (3×2^4)(4×2²) = (3×16)(4×4) = 48×16 = 768
4yx^6 = 4(3)(2³)(2³)
= 12(8)(8)
= 768
the following is also an answer if I replace the 4 with x²
yx^8 = 3×2^8 = 3×(2×2×2×2×2×2×2×2)
= 3×(2×2×2×2)×(2×2×2×2)
= 3×(2^4)×(2^4)
= 3×16×16
= 3 × 256
= 768 These calculations are the same
