√3(6√5 - 8√9)
= 2√3(3√5 - 4√9)
= 6√15 - 24√3
= 6(√15 - 4√3)
6â(5*3) - 8â(9*3) => 6â15 - 24â3
how do you multiply â3(6â5 - 8â9)?
â3(6â5 - 24)
6â15-24â3
âa * âb = âab
just multiply â3 by each term in the brackets
this will give you:
6â15 - 8â27
this can be simplified to:
6â15 - 24â3
a(b - c) = ab - ac.
a = â3
b = 6â5
c = 8â9
Substitute:
answer = 6â15 - 24â3
Distribute: 6sq rt 15- 8sq rt 27
6sq rt 15- 8 sq rt 9 * sq rt 3
6sq rt 15-24sq rt 3
