Bantuannya ditunggu no 3 sama 5 yaa makasih ^_^

Answer 1

3. a.y³×2y^7×(3y)²
=y³×2y^7×(3y×3y)
=Y³×Y^7×2×9Y²
=y³×y^7×y²×2×9
=y^(3+7+2)×18
=y^12×18
b.b×2y^7×b³×y²
=b×b³×y^7×y²×2
=b^(1+3)×y^(7+2)×2
=b^4×y^9×2
c.3m³×(mn)⁴
=3m³×m⁴×n⁴
=m³×m⁴×3×n⁴
=m^(3+4)×3n⁴
=m^7×3n⁴
d.(tn³)⁴×4t³
=(tn)^(3+4)×4t³
=(tn)^7×4t³
=t^7×n^7×4×t³
=t^(7+3)×n^7×4
=t^10×4n^7
e.(2p³)×3(p²q²)×5q⁴
=2×p³×3p²×3q²×5q⁴
=2×3×3×5×p³×p²×q²×q⁴
=54×p^(3+2)×q^(2+4)
=54p^5q^6
5. a.4^5×2^4
=1024×16
=16.640
b.(3²)^5×3^5
=3^(2+5) × 3^5
=3^7 × 3^5
=2187 × 243
= 445.441
c.4×3^5+5×3^5
=4×243+5×243
=972+1215
=2.187
d.(-125)×(-5)^6
=(-125)×15.625
= -1.953.125
