Answer:
the desire expression is 19multiply(3 tens)=19multiply30=570
Step-by-step explanation:
19 ✖️ 1ten=19 ✖️ 10=190
19 ✖️2tens=19 ✖️ 20=380
19 ✖️ 3tens=19 ✖️ 30=570
19 ✖️ 4tens=19 ✖️ 40=760
but here 760 is over the given terms 684,but 570 is the nearest value to the value 684
so the desire expression is 19 ✖️ 3tens=19 ✖️ 30=570
