minta bantuan nyaa ya

a.
4⁶ x 4³ = 4⁶⁺³ = 4⁹

b.
(-7)³ x (-7)² = (-7)³⁺² = (-7)⁵

c.
4 (-2,5)⁴ x (-2,5)³ = 4 (-2,5)⁴⁺³ = 4 (-2,5)⁷

d.
(5²)³ = 5²ˣ³ = 5⁶

e.
5² x (2/5)³ x (2/5)⁵ = 5² x (2/5)³⁺⁵ = 5² x (2/5)⁸ = 5² x 2⁸ x 5⁻⁸ = 2⁸ x 5²⁻⁸ = 2⁸ x 5⁻⁶

1.4^6+3=4^9=262.114
2.-7^3+2=-7^5=-16.807
3.(-2,5)^4+3=(-2,5^7)4=-70
4.5^2×3=5^6=15.625
5.(2/5^3-5)=(2/5)^-2=2^-2/5^-2=4/25=25/4
5^2=25×25/4
semoga membantu maad klo salah
