Question

What is the value of the expression when s=2 and t=1.5 -3|5-s3|+3t

Answer 1

Answer:

The value of the given expression is -4.5

Step-by-step explanation:

We need to find the value of the expression $-3|5-s^3|+3t$ when s=2 and t=1.5

Putting the values of s and t in the given expression.

So,

$-3|5-s^3|+3t=-3|5-(2)^3|+3\times 1.5\\\\=-3|5-8|+4.5\\\\=-3|-3|+4.5$

We know that, |-a|=a

So,

$=-3|-3|+4.5\\\\=-3(3)+4.5\\\\=-9+4.5\\\\=-4.5$

So, the value of the given expression is -4.5
