You might do it by performing the indicated multiplication.
Observe, as we demonstrate:
(-9) x (8) = -72
8/9
6 goes in 12 times. 8 goes in 9 times. 9 goes in 8 times.
its once and the raimander is 1
-0.8888 repeating
8 times 1 = 8 8+1=9
-9 x -8 = +72 negative x negative = positive
use a calculator :)
81
-3.375
-4/9 × 9/10 × -5/8 = (-4 × 9 × -5) / (9 × 10 × 8) = 180/720 = 1/4 or .25
it depends on what surd you have. Take root 72 for example, to simplify this, divide by a factor of 72, in this case 8, so that you are left with root 8 times by root 9. The root 9 can be simplified to just 3, and you will be left with 3 root 8 as your simplified answer
well a positive times a negative equals a negative so if the problem was -8 times 9 it would equal -72
8/9
9 + (-8) = 1
8
36/8 = 9/2
