Answer:
The value of the given expression is -4.5
Step-by-step explanation:
We need to find the value of the expression [tex]-3|5-s^3|+3t[/tex] when s=2 and t=1.5
Putting the values of s and t in the given expression.
So,
[tex]-3|5-s^3|+3t=-3|5-(2)^3|+3\times 1.5\\\\=-3|5-8|+4.5\\\\=-3|-3|+4.5[/tex]
We know that, |-a|=a
So,
[tex]=-3|-3|+4.5\\\\=-3(3)+4.5\\\\=-9+4.5\\\\=-4.5[/tex]
So, the value of the given expression is -4.5
